Fuck the nip, go for the jimson weed. Shit grows all over the place and it seriously fucks you up. Active ingredient is datura, I think. Hardcore shit, never did it myself but have seen people freakin out on it. Cannot remember what it looks like but if you use the search button for a descrip, you'll be able to find it close to your house, usually in fields I believe. The doctor will not be responsible for what happens to you however.
