What are the effects of cannabis?

The effects of cannabis are varied, the different strains contain subtle differences in the cannabinoid composition and many users develop preferences for certain strains. So, what are the effects of cannabis?

Cannabis has effects both on the body (physiological) and the mind (psychoactive). The physiological effects may include increased heart rate, reddening of the eyes, dryness in the mouth, reduced pressure in the eyeball (intraocular pressure) and muscle relaxation.


Psychoactive cannabis effects, also known as the 'high'.

The psychoactive cannabis effects are often referred to as the ‘high’ which may start within a few moments of taking the cannabis and typically lasts 2-3 hours. For many the effect of cannabis is a euphoric high that will include a relaxed sense of well being, pleasant changes in perception, enhanced appreciation of art, humour, nature, music, people and TV. Possible increased libido and appetite are common side effects as is the removal of anxiety. For the experienced user, higher doses may allow altered state of consciousness, enhanced distant memory recollections and even depersonalisation - allowing the user to ‘think’ outside of their normal self.

Cannabis use may affect the users attention and reflexes, the responsible stoner may prefer not to drive whilst high. The effects of cannabis can be magnified with alcohol and many users prefer to avoid mixing the effects of both.

Users may also note impairment of short term memory and adistortion in their perception of time whilst high. For users not accustomed to some of these effects of cannabis there may be a sense of anxiety or paranoia especially if they have exceeded their optimum ‘dose’.

Some users may feel sleepy towards the end of their high, and some medical strains such as Dutch Passions Ortega Indica have been bred to enhance the quality of sleep without the groggy ‘morning after’ feeling that sleeping pills can have.
