What Is Marijuana and How Does It Work?

Tetrahydrocannabinol (THC), a component of marijuana, acts both centrally and peripherally on endogenous cannabinoid receptors. Activation of cannabinoid receptors affects serotonin release, increases catecholamines, inhibits parasympathetic activity and inhibits prostaglandin biosynthesis.

Marijuana can be used to decrease intraocular pressure, analgesia, anti-vomiting (antiemetic) effects and as an appetite stimulant.

Marijuana is available under the following different brand names: Cannabis, Ganja, Hash, Hashish, Hemp, Mary Jane, Pot, Reefer, and Weed.

The United States (U.S.) Drug Enforcement Administration (DEA) classifies marijuana as a Schedule 1 substance under the Controlled Substances Act (CSA). Schedule I drugs are recognized as having a high potential for abuse with insufficient evidence for safety and efficacy with no currently accepted medical use for treatment in the U.S.

Marijuana is not approved by the U.S. Food and Drug Administration (FDA) for medical use in the U.S. and remains classified as an illicit drug by the DEA. However, several states have adopted individual State Medical Marijuana Laws including: Alaska, California, Colorado, Hawaii, Maine, Maryland, Michigan, Montana, Nevada, New Mexico, Oregon, Rhode Island, Washington, and Vermont.

In October of 2009 the U.S. Justice Department announced that it will no longer enforce federal drug laws on persons who use marijuana for medicinal purposes or their sanctioned suppliers, as long as state laws are followed.

Dosages of Marijuana Should Be Given As Follows:

  • Tincture: 5-15 drops or 1-3 drops of fluid extract.

  • 1-3 grains (65-195mg) cannabis for smoking, potency highly variable.
  • Drug deteriorates rapidly

How To Get A Marijuana “Prescription”

Updated on November 22, 2019. Medical content reviewed by Dr. Joseph Rosado, MD, M.B.A, Chief Medical Officer

If you’re wondering how to get a cannabis prescription, it’s important to first know that, you can not get a prescription for Medical Cannabis. Since it is still illegal at the federal level, technically doctors can not write a prescription for Medical Cannabis. However, they are able to write a recommendation for Medical Cannabis which you can then take to a Dispensary to get filled. Depending on the state you live in, your ability to obtain medical marijuana will depend on what type of condition you’re suffering from. Certain states do not allow people without these qualifying conditions to obtain medical marijuana legally. Qualifying Conditions vary from state to state so be sure to check with a doctor or your state’s Qualifying Conditions first. You need to check to see what conditions qualify for medical marijuana in your state.

What Is a Cannabis Recommendation?

Since marijuana remains illegal under federal law, doctors do not write prescriptions for medical marijuana as they would for other types of medicine. Rather, they write recommendations stating that a patient will benefit from medical marijuana as a part of their overall plan of treatment.

There are many states now that allow medical marijuana to treat a wide range of conditions, but many others only allow it for a certain condition, such as epilepsy or cancer.

How to Get a Cannabis Recommendation

As long as medical cannabis is legal in your state, it shouldn’t be difficult to find a doctor who can provide you with a recommendation for medical cannabis. The difficulty of the process depends on the state in which you live. You might need to visit the doctor’s office in some states, while in others you can schedule a video consultation online with a doctor who can give you a certificate of recommendation.

Who Can Authorize Medical Cannabis?

Any licensed doctor in a state where medical marijuana is legal can write a recommendation for a patient — provided the patient’s condition is on the list of illnesses that can be legally treated with cannabis. Once the patient receives a recommendation, he or she can purchase medical marijuana, possess it, consume it and, in some states, even grow it themselves.

Once you receive your recommendation, you will need to find a dispensary that can provide you with the marijuana you need. You’ll need to bring the certification, as well as your medical marijuana card, in states that require it. You will also need to have your driver’s license or other form of picture ID ready to prove that you’re a resident of the state where you’re obtaining legal medical marijuana.

It’s very important that you do some research into exactly what type of medical cannabis will be right for treating your particular condition. There are hundreds of different types of strains, as well as a variety of products that will help you consume the cannabis. Methods of treatment include edibles, tinctures, tonics and many others.

Staff members at your dispensary can help you determine what type of weed is best for your problem, as well as help you decide what method of consumption will best address your condition.

Medicinal vs. Recreational Marijuana Use

If you use marijuana recreationally — whether you’re doing so legally or illegally — you need to know about “self-medication.” This is the practice of using a drug for therapeutic reasons without the supervision of a doctor. Your use of the substance could be due to some underlying medical problem that hasn’t been diagnosed.

If you smoke medical marijuana because you’re depressed, have trouble sleeping or are suffering from pain, please talk to a doctor to make sure your issue is properly treated. Find a doctor near you today!
