So looking over the Minor Conjuration ability got me thinking. What about using the ability to conjure WereBear blood (in vial or not). Consume said werebear blood. Hybrid form transformation. For minimum the next hour, you can atk using the werebear's atks? Since it is you dealing dmg not the conjured item it should stick around for at least an hour. Maybe longer if the curse can count as permanent or hour if the conjured item "leaves" your body via Minor Conjuration ability.

Thoughts? As a DM I think itd be a blast to see.

In the context of Werebears specifically, I'm not sure I follow what the blood is supposed to be doing. You don't catch Lycanthropy from blood, you catch it from being bit and failing a con save.

PLAYER CHARACTERS AS LYCANTHROPES

A character who becomes a lycanthrope retains his or her statistics except as specified by lycanthrope type. The character gains the lycanthrope’s speeds in nonhumanoid form, damage immunities, traits, and actions that don’t involve equipment. The character is proficient with the lycanthrope’s natural attacks, such as its bite or claws, which deal damage as shown in the lycanthrope’s statistics. The character can’t speak while in animal form.

A non-lycanthrope humanoid hit by an attack that carries the curse of lycanthropy must succeed on a Constitution saving throw (DC 8 + the lycanthrope’s proficiency bonus + the lycanthrope’s Constitution modifier) or be cursed. If the character embraces the curse, his or her alignment becomes the one defined for the lycanthrope. The DM is free to decide that a change in alignment places the character under DM control until the curse of lycanthropy is removed.

The following information applies to specific lycanthropes.

Werebear. The character gains a Strength of 19 if his or her score isn’t already higher, and a +1 bonus to AC while in bear or hybrid form (from natural armor). Attack and damage rolls for the natural weapons are based on Strength.

And, that curse is not an immediate transformation, even if you embrace it willingly:

Curse of Lycanthropy. A humanoid creature can be afflicted with the curse of lycanthropy after being wounded by a lycanthrope, or if one or both of its parents are lycanthropes. A remove curse spell can rid an afflicted lycanthrope of the curse, but a natural born lycanthrope can be freed of the curse only with a wish.

A lycanthrope can either resist its curse or embrace it. By resisting the curse, a lycanthrope retains its normal alignment and personality while in humanoid form. It lives its life as it always has, burying deep the bestial urges raging inside it. However, when the full moon rises, the curse becomes too strong to resist, transforming the individual into its beast form — or into a horrible hybrid form that combines animal and humanoid traits. When the moon wanes, the beast within can be controlled once again. Especially if the cursed creature is unaware of its condition, it might not remember the events of its transformation, though those memories often haunt a lycanthrope as bloody dreams.

Some individuals see little point in fighting the curse and accept what they are. With time and experience, they learn to master their shapechanging ability and can assume beast form or hybrid form at will. Most lycanthropes that embrace their bestial natures succumb to bloodlust, becoming evil, opportunistic creatures that prey on the weak.

So.... unless I'm missing something about a special "Werebear Blood Vial" item... no you can't conjure that to immediately transform, or even to voluntarily become infected. 

But to take a step back from this "nonbo"... in general, can you use Minor Conjuration to summon consumables that provide a lasting benefit? 

Minor Conjuration

Starting at 2nd level when you select this school, you can use your action to conjure up an inanimate object in your hand or on the ground in an unoccupied space that you can see within 10 feet of you. This object can be no larger than 3 feet on a side and weigh no more than 10 pounds, and its form must be that of a nonmagical object that you have seen. The object is visibly magical, radiating dim light out to 5 feet.

The object disappears after 1 hour, when you use this feature again, or if it takes or deals any damage.

So, there's basically three restrictions: (1) an "inanimate object" (which I'm not sure "inanimate" is really doing any work there apart from "object", but could mean nothing with living biological components?), (2) of a certain size/weight, that (3) isn't itself magical (so, no recreating potions or ability-score-increasing tomes). 

I'm not sure there are any beneficial non-magical substances out there to conjure and rub on yourself, but if there were.... I don't see a problem with it? You've conjured a (temporarily) real object, so just like you could conjure a knife and cut off your toe and still have a missing toe after the hour is up... other changes you might undergo from conjured objects seems fine? I think that reading "inanimate" to prohibit active biological substances (poisons and diseases?) is too harsh, I'd totally let a Wizard conjure up some Purple Worm Poison or the like, what a clever idea and good way to make the Poisoner feat a strong choice! But I'm just not aware of any non-magical substances in a sourcebook so far that would give you a lasting benefit from consuming/using them. 

I don't mean to rain on your parade, but there's a couple flaws with this plan.

its form must be that of a nonmagical object that you have seen.

So first, have your wizard ever seen a vial of werebear blood?

Beyond that, lycanthropy isn't spread simply by drinking blood.

Curse of Lycanthropy. A humanoid creature can be afflicted with the curse of lycanthropy after being wounded by a lycanthrope, or if one or both of its parents are lycanthropes.

There is a Blood of the Lycanthrope poison which will do the trick, but it isn't actually straight werewhatsit blood -- that's just its main ingredient -- and it isn't an ingestible poison, but one you put on a weapon (so it needs to enter your bloodstream through a wound). Even then, you'll still have to fail a CON saving throw to be afflicted.

 All fair points and thanks for the hads up on that. I missed that it is a hit, but I think I was looking to much into the Blood of the Lycanthrope item (as AntonSirius pointed out)to hopefully get the wearbear one and that way transform into it. The moon part and not succumbing immediately I wonder if that is fully the case (yes you made an excellent case on the moon and after time controlling those urges). I just am unsure on its fully interactivity and length of time. Maybe I'm too tired or I caught the dumb haha.

I see it now, Blood of the Lycanthrope (Injury).

The sourcebook that's found in puts it in a section called "Magic and Special Items," so its a little ambiguous whether this blood is intended to be a "magic item" or a "special item." dndbeyond tags it as "equipment" but its antidote as an uncommon "magic item", but that's neither here nor there. I think the fact that the poison inflicts a "curse," and that a "curse" is generally understood to be a magical effect, would be a strong indication that this is a magical poison and not a biological one.... but I dunno, your mileage may vary on whether your DM would have it light up with Detect Magic, and prevent it from working with Minor Conjuration. If they let you conjure it, and if you've seen one to allow you to conjure it, and if you inflicted it on yourself, and if you failed the Con save... then yes, you'd have a curse that lasted beyond the duration of Minor Conjuration. Though, it looks like the published version only allows Wererat, Werewolf, or Wereboar, so fishing for a neutral good bear form might be another speed bump in this process. 

I don't see interacting with the conjured item and having its effect last as the obstacle here, I see conjuring the item in the first place as the obstacle. 

 All fair points. I know (I say know but more so seen in other places for uses, including the creation bard) poisons are a strong use of conjuring. I would totally allow it, granted I'm also the one thinking it up so both as a dm and player I want to see it done haha. Also even if 100% doable I realized an error, the blood can only be from wereboar, wererat, or werewolf. No werebear sadly (damn dyslexia). That means ceremony spell needed to change alignment back at the least, and hoping for that wereboar one. I think that is the best choice anyway?

The worst part that you didn't really consider fully is this: 
"If the character embraces the curse, his or her alignment becomes the one defined for the lycanthrope. The DM is free to decide that a change in alignment places the character under DM control until the curse of lycanthropy is removed."

Not only would you become Evil something (which arguably you kinda adressed with Ceremony... But why would a Evil character agree to be part of the ceremony? It has to be willing for it to work, which seems unlikely), but more importantly the DM will most likely make you an NPC while cursed.

So basically you just made yourself into an evil npc monster. 

Also, considering how incredibly overpowered it could be to be immune to damage like they are, it's very unlikely that they will add the "curse" of becoming a good aligned were-creature. 

I mean I can see both kinds being cool to play, the curse being a big part of the roleplaying and all that... But as a conjure item thing from a level 2 wizard? Nope. One could also argue that the actual vial is the item, not the liquid, in the same way it's described as multiple part items wouldn't work.
