I am 63 years old and stood at President Nixon's window in Washington DC in 72 with approximately 100,000 others shouting for pot legalization and ending the war in Viet Nam,,we scared hell out of him and have been paying for it since. Cannabis,,which is not a medicine according to the DEA,,is very effective for treating swollen joints and reducing nagging pains such as caused by arthritis. As people reach the age where these types of problems occur they may find a more effective medicine to treat those probelems,,but they will not find any safer.
