The war against drugs impedes Darwinian evolution.
1. Drugs are bad and used excessively - which in most cases they do due to their addictive nature- kills.
2. Feeble minded people with wanton disregard will disregard this fact and engage in imbibing drugs anyway.
3. Given time and access to drugs, these feeble minded individuals will die and be out of the gene pool.
4. Trying to stop them doing what they want will increase their supply in the gene pool.
5. Therefore drugs are good and should be legalized for all people of majority age, to use at discretion, just as alcohol is. People should be punished for what they do after taking drugs, just as they are punished for what they do after drinking, not for taking drugs.
