Legalization of recreational use marijuana is a terrible idea and legalization at the state level needs to be blocked federally.
Although marijuana has some medicinal benefits in pill form, marijuana smoke has 40-70% more carcinogenic hydrocarbons than tobacco and it took us until the 1950s to see a clear link between tobacco and cancer and then until the mid to late 60s for us to get the Surgeon General warning. legalization of marijuana will increase its use and abuse and result in the same lesson will be learned.
Plus, we don't have adequate ability to test drivers who might be impaired by its abuse so it will become a safety issue.
