What Are the Side Effects of Marijuana

Medical cannabis should always be used in a safe, monitored environment—ideally under the guidance of a licensed healthcare professional. Everyone reacts to cannabis differently. Factors like body chemistry, dosage, and method of consumption can all influence how it affects you. That’s why, if cannabis is being used for medical purposes, it’s important to do so under the supervision of a trained, licensed healthcare provider.

Some people experience mild effects such as increased appetite, dry mouth, or drowsiness. Others may find it causes anxiety, trouble concentrating, or short-term memory issues. When taken in high doses or without proper guidance, cannabis can interfere with daily functioning and overall well-being.

Edible cannabis often produces stronger, longer-lasting effects than smoking. Since THC is absorbed more completely through digestion, it can lead to greater physical fatigue, elevated heart rate, or disorientation if not properly dosed.

Over time, consistent high-THC use may alter brain chemistry—especially in young people under 25, whose brains are still developing. This can impact motivation, emotional regulation, and cognitive function. Cannabis use disorder, a form of dependency, may also develop in some individuals with heavy or prolonged use.

Do not operate heavy machinery, including vehicles, if you are impaired by cannabis. It can reduce reaction time and affect decision-making, increasing the risk of accidents.

Used responsibly and in the right setting, cannabis can support symptom relief for many conditions. However, understanding both its therapeutic potential and its risks is key to safe and effective use.
