You can get in serious shit just for a small amount of weed (not so much prison but losing stuff like your college grant, driving license and any entitlement to welfare benefits).
There was a recent scandal that a lot of hurricane victims were refused aid because they had been busted for small amounts of drugs years ago and were classed as being a criminal
but of course industrial solvents are easier to get hold in small quantities (the only restrictions on them being obvious ones to do with health and safety issues)
The reality of the war against drugs; people often end up going for more unhealthy options…
