How Does Smoking Marijuana Affect Your Weight?

Marijuana use has long been associated with incessant snacking. Smoking marijuana is known to increase one’s appetite – a sensation known colloquially as “the munchies.” Because of this common side effect, people commonly assume that chronic marijuana use causes weight gain.

Several researchers have tested this hypothesis in recent years with interesting results. While most studies agree that marijuana use affects your weight, the general effects vary from lab to lab.

Marijuana, Diet, and Weight Gain

smoking marijuana can trigger an increased appetiteA 2014 study in the journal Innovations in Clinical Neuroscience examined the effects marijuana had on weight. Their research revealed that individuals who regularly use larger quantities of marijuana (e.g., smoking two or three marijuana cigarettes, or joints) did take in more calories than individuals who smoked less or not at all.

However, this study also uncovered something paradoxical: People who smoked marijuana overall had a lower body mass index (BMI) than nonsmokers. The study was ultimately inconclusive, requiring more research, but these findings hinted that marijuana may affect your weight in a positive way.

These findings reaffirmed a 2011 TIME magazine report, in which scientists surveyed 52,000 people and found that 25 percent of nonsmokers were obese compared with 17 percent of marijuana users. The pervading theory from both these studies was that marijuana activates the brain’s pleasure center in the same way that food does. By smoking regularly, a person may sate the urge to overeat later.

Marijuana and Dietary Risks

Although the results of these studies may look promising to people who enjoy marijuana, it is still important to recognize the way marijuana can affect your health. Smoking pot may be healthier than overeating or using illicit substances, but that does not mean it is perfectly healthy.

A study in Preventative Cardiology discovered that marijuana use has been associated with an increase in:

  • Blood pressure
  • Cholesterol
  • Triglycerides

The study also mentioned that marijuana use often accompanied other unhealthy behaviors like drinking alcohol and using tobacco or illicit drugs – all of which have a negative effect on health.

These results indicate that, while marijuana use may not directly increase your BMI (or at least won’t increase it as much as overeating), smoking can cause cardiovascular problems that are often associated with an unhealthy diet. The result is still the same: an increased risk for cardiovascular problems.

Maintaining Your Weight

The most effective way to avoid health problems caused by marijuana use is to stop using marijuana; however, this is not always easy to do. The National Institute on Drug Abuse reports that around 30 percent of marijuana users are dependent on the drug. If you find yourself unable to cut back on marijuana use, you should consider entering treatment for an addiction to marijuana (also known as marijuana use disorder). Through treatment, you will be able to overcome an addiction to marijuana, improving your health in the process.

Studies indicate that marijuana does not trigger an increased appetite in test subjects until after two or three joints. Simply limiting the amount you smoke can help you maintain a healthy weight. Individuals who regularly smoke marijuana should also consider a regular exercise and diet regimen. This will help prevent compounding cardiovascular effects because of marijuana use and poor diet.
