Journal of Current Drug Safety on Cannabis' Possible Side Effects and Drug Interactions

Several key items of interest from the scholarly research found in the above article are listed below:

·         Cotton-Mouth

High doses of CBD can produce dry mouth, commonly called cotton-mouth due to the CB1 and CB2 receptors responding with inhibited saliva production. Drink water to solve.


·         High Doses of CBD and tremors in Parkinson’s patients

High doses may increase tremors in Parkinson’s patients. Low doses may improve tremors. Always consult a physician for proper dosage.


·         Low blood pressure

A small drop of blood pressure a few minutes after dosing may accompany high doses of CBD oil. Lightheadedness may be a symptom of the drop in blood pressure. Always consult a physician for proper dosage.


·         Hepatic Drug Inhibition involving metabolism

The liver enzyme, P450, may be inhibited from CBD. Enzymes metabolize almost 60% of synthetic or pharmaceutical or prescribed drugs, however one desires to label them. With extremely high doses of CBD, this can temporarily neutralize P450 enzymes and effect drug metabolization.

CBD can regulate blood pressure significantly, so a physician should be consulted to justify HBP medication dosage.

Consider also that highly acidic foods, like lemons or grapefruit also modifies metabolism of both CBD and P450 liver enzymes. It is not prescribed drugs alone that alter metabolism. A physician should always be consulted, especially for epilepsy patients taking clobazam in order to administer correct dosage levels.


·         Drowsiness and Alertness

Do not operate machinery or drive with higher doses of CBD as one may become drowsy. May be an effective sleep aid and restore natural circadian sleep cycle.


The majority of cases claim that CBD in low doses creates alertness.
