Druggies (legal or illegal substance abusers) need to just disappear. When one finds a new way to fuck themselves up, it catches on and policies are put into place that messes it up for everyone else. Like glue and paint. I enjoy building car models, which requires glue to make the parts stay together and paint to make it look complete. Both of which have restrictions on who can buy them because a batch of idiots decided to use it in ways they weren't meant to be used and screwed it up for the rest of us.
Worst part is those under 18 are not allowed to buy but most stoners are in their 20's.
I heard the fumes from burning duct tape can mess you up, so it won't belong before the most important repair tool becomes restricted.
