The federal government brought in marijuana prohibition over 80 years ago when a ban was placed on the use, sale or cultivation of the cannabis plant. Much of the motivation behind originally banning cannabis (while other more proven harmful drugs like cigarettes and alcohol were excluded) was institutionalized racism. Unfortunately, while it remains illegal under federal law, many states have legalized the use of marijuana for medicinal purposes. While we at Herb CEO strongly feel federal legalization and criminal record expungement is necessary, we are at least moving in the right direction with medical legalization. This legalization comes with a set of restrictions that you should be familiar with if your medical condition requires the use of medical marijuana. There has been extensive research carried out to understand the many benefits of medical marijuana. Some benefits include relief from some of the major side effects of chemotherapy like pain, muscle spasms and nausea. In addition to this, medical marijuana has shown promise when it comes to immune function, vascular health, digestive problems and even anorexia. If you are suffering from a condition where marijuana could help in alleviating some symptoms, you will be required to visit a doctor and get a prescription, which will make you eligible for a medical marijuana card. While it was difficult to get this card in the initial phases, the process has become much easier now, thanks to the legalization of medical marijuana in a number of states in the country.
