Green out

A ‘green out’ is an adverse drug reaction that can happen when a high amount of cannabis has been consumed in a short amount of time.

Experiencing a ‘green out’ or a ‘whitey’ can be unpleasant. This is when cannabis has been consumed in a large quantity very quickly, which can lead to fainting or vomiting due to a sudden drop in blood pressure. A ‘green out’ isn’t a medical emergency, but it also isn’t an enjoyable experience. In order to avoid them, always take medical cannabis as prescribed, by following the dosage instructions from your clinician.
