hodad, I spent twenty years at the bus station, or Transit Center downtown, watching all those you speak of 8 hours, or more, each and every day.

One.

Alcohol is, by far, the primary, and most destructive substance utilized by the vast majority of the "scary" characters there, bar none.

Mental illness follows closely as second, and the rest, save regular "bonafide" riders, of course, are made up of either predators, or the victims they seek out.

"Loco Weed", not so much.

But.

As it always comes down upon, it is NOT the substance, it is NOT the tool utilized, it is ALWAYS the INDIVIDUAL that utilizes, and abuse said substance or tool unto the detriment of others, rather simply themselves that matters, no?

The substance within itself causes no harm unto others, nor does the tool.

It is the INDIVIDUAL that utilizes said substance or tool that chooses to harm others rather than themselves only, and no amount of regulation will EVER change that.
