But there are strict laws surrounding these drugs, how can people still readily get such easy access to drugs?  I thought making drugs harder to get, resulted in less drug use??

For example, teenagers can easily get their hands on marijuana, yet it's totally banned and prohibited. 

The right wing loves its war on drugs, the left wing loves its war on guns.  Both have and will continue to be proven as ineffective in achieving what they purport to set out to achieve.
