Most use marijuana for one reason...to get high, period.
The "medicinal" use is just a ploy to get it more accepted and legalized, at least IMO. I know that is an "all inclusive" statement and I know that marijuana can be used for medicinal purposes and is effective in certain medical situations.
BUT, like alcohol, the main purpose is to get the euphoria and "buzz" that comes with the substance. It really is that simple to me.
Like most causes that people are championing the ancillary benefits of the situation are added in to make it more palatable and less sinister to get the goal accomplished. In marijuana's case, it is to get it legalized under the guise of the "benefits" it carries with it.
I am in favor of its legalization across the board. Don't care what it is used for or why someone would smoke it. I believe it is no more of a danger (and maybe less) than pounding down a bunch of beers or mixed drinks. If people want to be trashed and get wasted then that's up to them. Of course, that goes with the caveat that they don't endanger others by driving their car while being trashed and wasted, for instance.
The health care costs from abusers being physically affected won't be any different than rehab for alcohol, pain killers or any other substance that people already abuse anyway. Rugby had it right as far as those issues being present, madness, power and control.
It is a complex issue due to many, many years of laws and control of what drugs are legal/illegal and those in control won't let go easily. The "war on drugs" for the last 25 or 30 years is a farce and has done NOTHING to stop anything.
As far as the NFL guys continuing to be caught doing it, they are stupidly ignoring the consequences for the pursuit of selfish pleasures. As I said before, they just want to get high, period. It isn't to soothe their pain or medicate themselves, it is to be wasted. At least, that's what I think.
As long as it is illegal and as long as the league determines that it is not acceptable, then the players take the risk and must live with the consequences. Until that changes they will forfeit their privilege of playing in the league for a while or, eventually, permanently.
Maybe this wasn't the forum for all of that but I get tired of the excuses, the arguments over the penalties and the constant rationalizations of why it SHOULD be OK in these cases. It ISN'T OK at this time, it is illegal and that's the fact. Maybe it will change but until it does the players need to "just say no" until it does.
Forgive my soap box diatribe, but I had to vent. Sorry if it offends anyone, these are just my thoughts.
