The Impact of Medical Marijuana on Pharmacy Practice

Objective: As health care providers, it is important to recognize the potential health issues associated with marijuana use and to educate patients appropriately. As with other types of medication, marijuana has drug interactions, side effects, and the potential for toxicity. In addition, as with other substances that are abused, marijuana has the potential for dependence and addiction. The expanding use of marijuana will increase the pharmacist's involvement with marijuana as part of a patient's regimen. The objective of this paper is to educate health care providers on potential counseling points for patients in regards to side effects, drug interactions and other potential adverse effects from marijuana use. Summary: Currently in the United States, 29 states (plus Washington D.C.) have passed laws allowing for the use of medical marijuana. The possession limit and form of marijuana varies by state. It is imperative that pharmacists understand the laws in their state and the overall effects of marijuana. Conclusion: The increased legalization will continue to expand marijuana's use among patients, necessitating health care providers to be well informed regarding marijuana's side effects, drug interactions, and addiction potential.
