What exactly are these effects?

The effects of using cannabis can be quite unpredictable and vary from person to person. Some users may feel extremely anxious and fearful when "high" while others feel euphoric, relaxed and/or talkative. Similarly, some individuals find that they enjoy the perceptual distortions caused by cannabis while other people find these effects to be unpleasant for them.

Each experienced is based on many factors including: age, mood, expectations, environment, medical or psychiatric conditions, the amount of cannabis taken (dose), whether the cannabis is smoked or eaten, how often and for how long cannabis has been used and use of other drugs (including alcohol, non-prescription, prescription, and street drugs).


Some typical physical short-term effects include:

-      red eyes

-      dry mouth and throat

-      increased heart rate and decrease in blood pressure

-      irritation of the respiratory tract (with smoking)


Some typical psychoactive short-term effects include:

-      drowsiness, relaxation, sense of euphoria

-      increased  awareness of sensation (e.g. taste "the munchies", listening to music, looking or creating art, etc)

-      altered state of consciousnesses, creative or philosophical thinking

-      metacognition and introspection

-      mild paranoia, anxiety or panic

-      altered perception of time and space


Some typical neurological short-term effects include:

-      impaired reaction time, coordination and motor skills

-      impaired short-term memory

-      decreased attention span


Some less common effects include:

-     hallucinations, pseudo-hallucinations (seeing colours or patterns that the user knows are not real)

-      severe agitation and abdominal pain

 The likelihood that these effects will be experienced goes up when the amount of cannabis used is also increased.
