How to Avoid the Most Common Medical Marijuana Side Effects

As with most medications, medical marijuana can have a range of side effects depending on the dosage, strain, strength, and route of administration into the body. Here at PA Medical Marijuana Doctor, we want to educate all of our patients about these side effects, and how they can avoid suffering from them, if possible. We’ve created this post to highlight four of the most common side-effects, and how to prevent them.

Increased Heart Rate

After consuming marijuana, heart rates can increase, peaking around 30 minutes after use. The more significant the dosage, the more the heart rate can be raised. Also, vaping makes the heart rate increase even more than smoking marijuana. Although there is no evidence that this could cause a heart attack, if you already suffer from heart problems, it’s recommended that you speak to your doctor for advice on medical marijuana dosage and administration.


When THC binds to the endocannabinoid receptors in our brains, it can have a sedative effect on some users. Certain strains of marijuana may be more likely to cause drowsiness than others. Also, some delivery methods, such as edibles and patches, can increase symptoms of drowsiness. Switch strains or delivery methods if you are experiencing drowsiness. Alternatively, take medical marijuana at bedtime and always avoid driving while under its influence.

Dry Mouth

As THC binds with receptors that affect the flow of saliva, up to 25% of cannabis users report having a dry mouth. To reduce the chances of this condition occurring, drink plenty of fluids before, during, and after marijuana use. Alternatively, chew gum to stimulate the production of more saliva.


Any medical marijuana product that contains THC can lead to dizziness in patients. THC helps to increase sensory perception, magnifying sounds, smells, and sights. This sensory overload can lead to a dizzy feeling in up to 60% of medical marijuana patients.

If the symptoms of dizziness are proving hard to cope with, try lowering your medical marijuana dosage. Other than that, try using edibles instead of smoking, since the effects of edibles come on much slower than smoking marijuana.

Step 1: Get Registered

Create a profile in the PA state Medical Marijuana Registry. This includes basic personal data like your name, current address, and contact information. You must have a Pennsylvania driver’s license or state ID card. 

Step 2: Get Certified

Schedule a consultation with PA Medical Marijuana Doctor to meet with a PA state-approved physician who can certify that you suffer from one of the qualifying medical conditions to participate in PA’s medical marijuana program.

Step 3: Get Your Patient ID

Once you’re certified by an approved physician, return to the Medical Marijuana Registry and finish filling out your application for a medical marijuana ID card. Once you receive your card, you can purchase medical marijuana from a dispensary.
