Side effects can vary from the type of cannabis product being used and the way it is being taken. For example, smoking a joint is different to vaping weed, cannabis oil or wax concentrate, and different again from using and taking CBD in tincture form or applied topically.  The most problematic side effects could be seen as a result of smoking or vaping, but ingesting large amounts of cannabis can also result in a psychotic episode for some people, such as those with a bi-polar condition of schizophrenia. The type or form of cannabis, method of consumption and quantity are key, along with the state of mind of the user and any pre-existing mental or physical conditions that could be aggravated. Again, it comes down to an individual person’s reaction and it can be said that cannabis is not a plant medicine that works universally, in exactly the same way, for everyone. It can be very subjective but worth trying for relieving different health issues. We always advise seeking medical advice first, using cautiously and being aware of dosage.  The old axiom “less is more” may also be worth keeping in mind when treating a condition for relief and control of symptoms.  We also recommend buying reputable products from accredited producers with accompanying lab reports, and if you have approved cannabis dispensaries in your state, these would be a preferred source which should offer good product and good advice. Some side effects for smoking weed beyond moderate use (and to a lesser extent vaping weed) that may be experienced, could include: headache dry mouth fatigue dry eyes increased appetite (commonly called “the munchies”) coughing dissociation or altered state syndrome an altered sense of time dizziness or lightheadedness high blood pressure impaired memory (think of binge drinking) Be aware that people react differently to amount and cannabis in general. Some people will have no problem smoking a joint, but others may find they experience a bad reaction, especially if an unseasoned smoker. In VERY high doses, weed can cause hallucinations, delusions, or psychosis, but this is rare and dependent on the strain, and not really normal. Some experts believe that people who experience psychosis when using marijuana may already be at risk for psychosis, so the use is simply exacerbating a pre-existing condition. People suffering from bipolar disorder may find weed might worsen manic states. Frequent use of marijuana might increase depression symptoms and the risk of depression, though it must also be remembered that careful use of prescribed weed can also treat and improve depression problems and PTSD. Hallucinogenic plant medicines can make the user come face to face with internalized and repressed mental conditions, so be aware of this. If you have a mental health condition and are planning to use cannabis to help with the condition, then it is worth considering a discussion with you therapist or doctor first when ‘going it alone’ could be unpredictable and can mean some risk on an unpleasant reaction. Finally, if you taking any medications, either prescription or over-the-counter drugs, it’s worth checking to see if there are any possible contraindication issues of mixing cannabis with a prescribed drug. Unwanted interactions can occur and this again means it is wise to check with your doctor first. Be aware that weed can amplify the effects of alcohol and other recreational drugs, negatively interact with blood clotting medications, and increase the risk of mania in people who take SSRI antidepressants. We again advise talking with your doctor about the medications and supplements you are on, and whether there would be any known adverse interactions with weed or other cannabis products you are considering.
