A herbologist or herbalist is a person who studies how plant essences can be used to help heal and treat ailments and heath issues.
This kind of herbologist studies marijuana and smokes it to help heal or treat themselves, or just wants to relax a bit and maybe eat some munchies. If you smoke pot for any reason, then buy this t-shirt and get free samples of weed from everyone you meet. Maybe not, but it's worth a try.
