Mescaline. I can't find it here (Victoria, British Colombia, Canada). Doors of Perception is good man. Books are better than drugs. I just read one with a mescaline trip in it- Beyond the Outsider by Colin Wilson. He didn't like it. But it was really pure (which can make you pretty sick) and he didn't take enough. He's usually a pretty smart guy. Luckily Peruvian Torch and San Pedro and Peyote are semi-legal in Canada. But I'd rather have synthetic garbage.
Schedule I is Completely illegal to produce, sell, distribute, and possess.
Schedule II is a substance that has medical value, but has high abuse potential. Schedule II substances are closely watched and are a hassle to deal with. Adderall, Oxycodone, methamphetamine, and cocaine are in this category.
Schedule III is a substance that has medical value but has a lower abuse potential.
Schedule IV is the same with even lower abuse potential.
Schedule V is a substance that is medically useful and has very low abuse potential. These are usually available behind the counter at a pharmacy without a prescription, but many pharmacies don't sell these because they don't want to deal with the liability.
man, even tho DMT naturally occurs in every animal on the planet its still a schedule I. every single person/animal has a 5-MeO DMT trip every night while they are sleeping and dont even know.
