It's crazy how tolerance and addiction are sociological as well as pharmocological and biological factors. I've been on month-long dope binges and, like oxy says, at any given time in the day, the same size sprinkling of gear on foil gave me a rush. Didn't get much in the way of WD's after. The situation kinda reminds me of twats on X who are all, "I'm not high I'm not high, these pills are shit" as they march around, teeth grinding, pupils huge.... well we get these people over here a lot lol
