am new to these chemicals

In my day there was only mda and I loved it. can i still get it? is it legal? is there a legal chemical i should not miss trying during my short absence from total soberiety - occationally happens. older guy here. and if so... someone hook me up. reading this forum is like graduate chemical class. In the old days I loved shrooms, mda, coke, some pot, and booze. as well as downers. you guys got suggestions? Please help an old druggie enjoy his "outing" from soberiety. and no freak out panic drugs please.
