There are other names for cannabis in the market such as marijuana and hashish.Inhalation considers to be the most common way for consumption.As the inhaled cigarette which called in some communities(joint)contains 0.5 to 0.7 g of delta-9-THC,but the most common dose contains 5-25 mg THC.It can be smoked directly or through small pipes[6].It was demonstrated that the physiologic effects result from oral consumption are slower in onset and have longer duration compared to that with inhalation administration.As a consequence,the patients may lead to ingest more cannabis and be affected more strongly and for longer than intended.There are other products considered to increase the risk of toxicity such as tinctures,capsules and topical.These preparations are limited in use.Furthermore,the additional chemicals and adulterants participate in a particular way to increase the risk of toxicity.As most of cannabis users are unaware by the presence of these chemicals.The only way of identification is when the user subjected to toxicological evaluation as part of a forensic investigation,for example,if being arrested for driving while under the influence of cannabis[3].
