Overdose of marijuana
Marijuana is a derivative of cannabis (cannabis). The main active substances are cannabinoids - these are compounds that have a psychotropic effect. Other names of the drug: hashish, anasha, ganja.
The grass is smoked, breathed in pairs, hash oil is consumed inside. The latter method most often leads to an overdose of marijuana, as the oil from hemp is added to the confectionery. You can put an excess amount of the drug in the product or eat too much. Since the problem is urgent, we will talk about the signs, consequences of poisoning and methods of first aid.
The effect of marijuana on the body
Drug activity is determined by the content of THC (tetrahydrocannabinol). The threshold dose is 50 mg / kg of body weight. Signs of intoxication appear when using 150-200 mg. THC at a dose of 300-400 mg causes confusion and hallucinations. Symptoms of overdose appear if the dose is exceeded at least 2 times. The maximum concentration of marijuana in the blood is reached after 1 hour and 10 minutes. The action lasts up to 6 hours, depending on the method of using marijuana and the amount of THC in it.
THC enters the bloodstream, where it binds to plasma proteins or is delivered to the cells. First of all, marijuana affects the brain. Hemp poisoning is the result of changes in the biochemical and metabolic processes in the body. This disrupts the synthesis of RNA, DNA, proteins. Cell activity changes, some body functions are suppressed: mental processes are disturbed, motor activity changes, and mental disorders are characteristic. In addition, cannabinoids stimulate the production of serotonin: mood improves, euphoria appears.
The mechanism of action of THC is to suppress the formation, release and destruction of acetylcholine - a neurotransmitter involved in neuromuscular transmission, plays a leading role in the parasympathetic nervous system that regulates the functioning of vital organs, especially the heart. Cannabinoids contribute to an increase in heart rate, provoke an increase in blood pressure, there may be pain in the region of the heart. Sometimes taking the first dose with appropriate comorbid conditions can result in a hypertensive crisis.
In violation of the formation of acetylcholine disrupted the work of other organs: lungs, digestive tract, salivary glands. The innervation of the iris is impaired. When using large doses, all effects are multiplied.
Death from an overdose of marijuana is theoretically possible. But for this you need to use a dose of 40,000 times higher than that which causes narcotic intoxication, therefore, to die from marijuana is unrealistic.
