You can grow Phalaris, I did, it's easy. I've also grown a ton of shrooms, high-THC weed, and made MDMA, LSA, EVE, DMT, and LSD. I recommend with any illegal that you do it yourself and on a small, undetectable level.
But a word of warning. DMT-ish tryptamines (phylaris, ayuhasca, etc.) are incredibly potent. If you don't have some previous psychedelic experience, they may take you too far out and you might not return. They called DMT "the businessman's trip" in the 60's b/c you go from zero to 60 in two minutes and com down within an hour. If you've never peaked on LSD, you don't know what this means. You can literally fill you shorts full of shit on the way up, and people watching you might think you're in a coma or a seizure.
But to be frank, shitting your pants may be the least of your worries. I started doing LSD at 16, after reading a million pages about drugs, based on a lot of factors. It seemed to have the highest "payoff" for the least price and side effects. I never got heavy into addictive drugs or alcohol (tried EVERYTHING though). Even after years with LSD, I was not prepared for the DMT experience. Salvia is similar. Of course, low doses are much more controllable. High doses of these substances take you to places you will never understand. PM me if you want the blow by blow of what to expect, but trust a person of experience when I tell you that stronger minds than mine have been broken by low doses of this shit. Salvia is no joke either, especially the higher concentrated versions. I have had experiences so intense that coming down threw me into month-long depressions--> I literally got so high that reality became a giant bummer.
Just remember-->to get to the "vision" level of any psychoactive, you need to essentially posion yourself and your mind, and this can be a very volatile experience, and you may never be able to interpret the meanings in a sober contest. This is why I quit doing drugs all together.
If hallucinating is what you are after, be aware that to get there you will lose a huge measure of control to reach that state, and this has been known to fracture people's psyches indefinitely. You know, it's all fun and games to see fractals and patterns and stuff, but when your vision dissolves into images of family members killing you, or worse, and you can't make it stop, you may regret your choice to eat a half pound of phalaris grass.
My belief is that hallucinogens are the fabled fruit of knowledge from the garden of Eden, and can kill as easily as enlighten, and should therefore be taken with the utmost of caution if at all. I don't touch any of it anymore.
