In response to a remark made in post #9 that people can indeed already obtain marijuana, so why make it legal for medicinal benefits--
1. If marijuana is legalized, the contents can be controlled. Nowadays marijuana is often laced with other substances. If people could grow one or two plants themselves, there would be pure marijuana that they could have, or if they purchase it legally, the marijuana will be pure.
2. More importantly, if a person uses marijuana for relief of pain etc. but applies for a job, he/she will have to submit to a drug test. Now, if marijuana is not legal, then the person will be denied employment opportunities, not to mention anything other legal ramifications that may result. So, having a legal substance that provides medical benefits is of paramount importance to such a person.
