Actually, not forgotten friend. The term "endorphin" implies a pharmacological activity as opposed to a specific chemical formulation. And "adrenalin" is a good fix for certain occasions.
Though not normally thought of as "drugs" they are all neurotransmitters that have a lot to do with the action of all the different psychedelics being mentioned. So you just figured you would cut out the middleman and get right to the transmitters involved, heh? Reminds me of the day my when 8 year old daughter was playing around with an EpiPen and set it off into her thumb. She was so scared and jacked up on epinephrine that I was having a hard time keeping a straight face while trying to calm her down. At least she has never fucked around with the first aid kit again.
