Can a rabbit get high from marijuana?

It is not safe to give any kind of drugs to an animal except on strict veterinary advice. It is also not safe to give foods intended for humans to an animal.

If you have around you the sort of people who might consider it amusing to give harmful substances to captive pets, avoid these people and keep your pets well away from them. These are not sensible, nor well-intentioned, people; they are not friends, and they are concerned only with having a couple of minutes' fun for themselves, rather than with any consequences to others.
