Not fair on the tax payers?
Decriminalization and legalization haven't been shown to lead to increased use (which makes sense, because people will take drugs whatever their legality).
The costs of fighting a 'war on drugs' outweigh the costs of not fighting it.
Not treating people with addictions ends up costing more than treating them.
Not taxing the legal sale of drugs 'costs' more than taxing the legal sale of drugs.
Incarcerating people for the possession of drugs, which in many cases (weed, lsd, mushrooms, etc) are not going to cause harm to others, costs more than not incarcerating them.
Letting the profits of drugs sales, which you'll never be able to stop, go to criminals, means more powerful criminal gangs, which cost money to deal with.
The costs of educating people, which should be happening regardless of the legality of drugs, are massively outweighed by the costs of not educating people.
The arguments about the 'costs' of legalization and decriminalization are so fucking stupid. The 'I DON'T LIKE DRUGS SO NO ONE SHOULD DO DRUGS' brigade are far more tolerable than those that spout this bullshit.
1) Bullshit. There are plenty of people that have, or have lost, addict friends and family members that campaign for more sensible drug laws.
2) The societal repercussions, which are actually lessened by decriminalization/legalization?
Just look at the fucking facts. Jeez.
