I agree. But the problem is that after decriminalization
state will be tempted to repair its ailing finances by taxation
of these drugs. Which implies monopolistic control of them.
The government of Uruguay has taken the right step in this direction. There, the government has made weed available for less than $1 per gram. Here the consumers are getting benefited, as they are getting quality weed for so cheap, while the government is also saving money, by not having to spend its tax funds on police operations against the drug smugglers.
