A candid commentary on drug dealing, and the anecdotal reality of same. I have known 3 drug dealers in my life.
1) Stupid university kid who would buy a largish amount of pot, and break it down into small bags that students were likely to buy. Through skivving and maybe adding in a little oregano, he was able to skim enough profit to smoke himself for free. We're talking gross revenues of maybe $1000 a month, of which I would estimate 25% was 'profit'. Presumably he has moved on to being a pot-using productive adult, not dealing drugs later on in life.
2) Successful businessman in the jewellery trade, bought a notorious bar/hotel with proceeds from jewellery business. Became a cocaine user. Decided to get involved with the business of cocaine. For awhile, was wildly successful, and I knew him to be rather flashy, bought and wrecked a brand-new 280SEL. His own use became out of control, and he had too many 'hangers-on' and he was too generous with the product. Got into legal troubles - not so much from the dealing, although he definitely felt under pressure from the police, but he stopped paying taxes on his legitimate businesses. Eventually lost both the bar/hotel & his jewellery business, ended up buying/selling antiques & junk at the flea market. Quit cold turkey when he just couldn't afford it. Came into some money after 4 years of not using, went out and bought an 8-ball, OD'd and died.
3) Older gentleman (in his 70's) has a legal medicinal MJ grow licence as he is nursing his adult son through late-stage MS. He is permitted to grow 25 (!) MJ plants, and be in possession of the proceeds of same. This is obviously far more than one person can use. So, word gets out that he has surplus. The kid who mows his lawn doesn't get $20, he gets a little party loot bag. Some more organized individuals take the bulk of his surplus off his hands - to the tune of about $1500 a month. Presumably this product goes about 20km south into the US. Nice little income addition for someone on a pension, and essentially zero risk of getting in any serious trouble.
What would 'legalization' of drugs change in any of the above three scenarios? For legalization, read the definition put forward by Eddie Dane.
In case #1, he may or may not be out of business. Considering the barriers to growing and repackaging marijuana, it is plausible that if this person is motivated to make a couple of extra hundred a month, he would find a way to continue to do so. Also, I posit that this person poses no 'threat' to society - he's not selling 'hard' drugs, and has no inclination to do so - he's just supplementing his income in a very minor fashion. No worse than the guy who buys stuff at garage sales to sell on Ebay, except for the commodity involved.
#2 - This sort of operation, of the dangerous and harmful to society nature MAY be rendered unfeasible under a legalization structure. However the end result - of someone ceasing to be a valuable member of society, living marginally, and in the end dying an untimely death would likely not be solved. It might take longer, the slide may be more gradual at $50 a day instead of $1000 a day. However my understanding of the drug involved, and watching & knowing this person over a period of about 10 years implode, suggests that legalization may make the process look a little less seedy, but would have the same end result.
#3 - Less victimless than the example #1. That's a sizeable chunk of tax-free income my friend is earning, that isn't something that should be overlooked. Likewise, if the legalization scenarios we're bandying about here aren't applied at least on a continental scale, if not a global scale, then the issue of cross-border traffic - whom my pensioner friend is contributing to - will remain a major problem. Again, is what he's doing acceptable? I don't think pot is that big a deal, and certainly he individually isn't involved in any 'hard' drugs. However the people who are buying up the surplus may well be - they're sufficiently well organized to run this stuff across the border. Would legalization end this sort of trade? Only if adopted at minimum by Canada, US & Mexico. And even then, H. is still going to grow his 'tomatoes' rather than pay someone for the stuff his son smokes. And he'll probably grow enough to remain under the police radar, but still enough to make sure that friends & neighbors know where to go for their party favors. Not a big deal - people make their own beer & wine, maybe pot should be treated the same way.
