I'll be 45 this year, I was a late starter, started taking it when I was about 30. We used to batter it then, usually taking something Thursday thru Sunday. Part of the buzz was trying to score and when you did, it made it all the more sweet ! But I'm not sure if that was a craving, just being a little crazy !
I still do but not as much, perhaps once a month, but the sessions could last 12 - 18 hours.
I think if laws was relaxed, I believe usually grow up or grow out of it.
