I used to do crosstops like a fiend. Ordered like 4000 a month from the back of High Times. Sold them in 50 packs at about a 300% profit. I was doing 400+ a month. At least 15 a day. The tingly scalp thing. Was sleeping maybe 15 hours a week and about once a month I'd cash for about a day and a half. There were folks worried about my safety.
