Because THC affects the hippocampus amygdala, and cerebral cortex it can cause short term problems with thinking and memory function.

Disturbed Balance and Coordination

THC affects the areas of your brain that are responsible for balance and coordination as well as reaction time. This can impact users ability to drive and operate machinery as well as simpler tasks such as walking and talking.

Increased Appetite – The Munchies

Increased appetite can be a positive effect for some and cannabis is often used to help those who are experiencing a loss of appetite due to a variety of illnesses. Of course, for others, this can be seen as a more negative side effect.

Cannabis increases appetite as well as increasing the enjoyment of food and heightening the sensory experience of eating. It is thought that smoking cannabis triggers the release of the same hormone your body produces when your stomach is empty so marijuana can make you hungry even if you’ve already eaten.


One possible side effect of marijuana is either audio or visual hallucinations. Hallucinations are not a very common side effect however and tend to only happen when THC does are high.

Anxiety and Depression

Anxiety or paranoia is one of the more common side effects of cannabis. However many people also use cannabis to help them deal with anxiety due to its relaxing effects and the fact that for many people it promotes sleep.

Cannabis has also been linked to depression although there is little conclusive evidence to support that smoking causes depression.

If you are using cannabis and your mental health appears to be suffering for unexpected reasons you some research suggests you may be better off with medicinal strains that have a lower THC content. You can apply for a doctors recommendation online today.

Bloodshot Eyes

Bloodshot eyes or red eye are another common side effect of smoking or consuming marijuana caused by changing blood pressure making the blood vessels in your eyes dilate. Again this is not always seen as a negative side effect and is one of the reasons cannabis may be useful in treating glaucoma.

Bloodshot eyes are not generally anything to be worried about and although they are a tell tale sign you have been smoking it doesn’t appear to do any long term damage.
