Even a "safe" dose will make you feel terrible. It might cause a psychotic break that'll permanently mess you up. Theres people cutting of body parts or getting into accidents because they are delirious and cant make sense of their environment. You might think you are at home talking to your mom when in reality, you are out in the park talking to a tree. You will not be able to tell apart whats real and whats hallucinated. You might encounter dog sized spiders and are completely convinced they are real. Youcan lose complete sense of time, space and youself. A lethal dose is very close to an active dose and potency varies a lot. The same amount of plant matter might be weak one time and deadly another.
If you really insist on trying for a darwin award, harvest a big amount of either leaves, flowers or seeds, dry them, grind them up and mix well. You now have a batch of consistent potency. Try a small dose. See how it effects you. Wait at least 3-4 days, then try a slightly bigger dose (it takes that long for the alkaloids to leave your system). Smoking is safer than ingesting.
Once you get to doses that are more psychoactive, get a responsible tripsitter that is able to look after you for a full day or two.
