SEVERAL times.
I watched him go from a hard working man with lots of money, to a broke ass junkie who lived with his wife's parents...this all happen over about 3 years.
one day he's doing bumps to get better workouts, a few years later he's main veining coke and smoking meth.
I've seen this happen all too many times. I used to run with a pretty heavy party crowd in my early years. These guys and women were all young professionals, doctors, lawyers, business owners, entrepreneurs etc, but they all partied WAY too much. Most of them started out with just drinking, moved into doing X and then on to coke and GHB. I got out of that scene after a couple of years, I never got into recs really. I later found out that out of the 15 or so from the group, 8 were dead and the rest were either in jail or had moved out of state to get away from it all. One of the main guys was this 40 year old who was a dealer as well. He got busted with 10,000 X pills. Went to jail for a couple of years, got out then got busted again for making GHB in his sink, the feds were still watching him. The guy was a very successful dude who had his own business, only had to work about 20 hours a week and was doing about $300,000 a year which was really good fro the area. One other guy who was a really young up and coming defense attorney hung himself in his living room after getting disbarred for showing up in court blitzed out on coke.
Glad I got out of that shit when I did, really fucking sad to see people do that to themselves when they have so much going for them.
