I'm 62 but even 44 yrs ago I was aware of the psychosis inducing effects of meth/speed (back then). That was enough for me to conclude that I wanted nothing to do with the drug or the people using it. Since then I've seen so many crazy methed out tweaker *ucks ruin others lives all the while being accepted by the enablers around them. It increases productivity after all. Who cares if they are a bit over the edge? Twump reminds me of a meth monkey. Down to the jaw and mouth movement.
