The idea
Prohibition doesn't work, and so far as I can find out, cannabis does less harm than tobacco or alcohol.
I don't have as much information on other drugs, but I wonder if ecstasy does worse harm than tobacco or alcohol. If not, legalise that too.
I am sure others have suggested this, but did not have the time to read their entries in detail to make sure I wasn't endorsing other views I wouldn't agree with.
Why is it important?
It's important because
- arbitrary laws (penalising one drug but not another) make our legal system less worthy of respect
- activity that harms only the user should not be criminal
- we could save the cost of enforcing the laws against cannabis.
