(forget P2P but it should work for 4-Me-P2P)
4-Methylamphetamine is described in PiHKal and it seems a bit more toxic than unsubstituted amphetamine, 150 mg gave signs of mild toxicity such as salivation, coughing and vomiting. It may be wise to keep this in mind when tasting the untested N-methyl analog.
