What is Marijuana? An Overview
The strength and potency has increased greatly through advances in genetic manipulation and growing conditions (hydroponics), and today’s
The main active ingredient is Delta-9-Tetrahydrocannabinol (THC), which binds to the CB1 receptors of our cannibanoid systems in the brain and throughout the body. It is the THC that gets you high, and it is the THC content that has been steadily increasing over the past decades.
Although THC is the primary intoxicating active substance, there are an additional 400 active or semi active substance present in varying degrees in different strains of
These 400 active molecules also seem important for the drugs efficacy as a medication, and although scientists have synthesized THC in a pill form, the absence of this comprehensive mix of other chemicals seems to decrease the usefulness of this synthesized medication.
After smoking, the THC and other active chemicals are absorbed through the lungs and passed quickly into the bloodstream; and within about a minute the effects of the THC start to be felt. The intensity of the high will continue to increase for about 20 minutes, before plateauing and gradually leveling off over about 2 hours.
When you smoke, the THC absorbed into the bloodstream passes into the brain and attaches itself to receptors in the endo cannibanoid system, a system found throughout many higher order parts of the brain. Once these receptors in the brain are stimulated by THC, the user begins to experience changes in sensory perception, in time perception, in concentration and cognitive abilities, in coordination, and in appetite. The endo cannibanoid system is linked to the pleasure system of the brain, and when activated it causes a dopaminergic reaction, allowing for pleasurable and relaxed sensations in addition to these other sensory alterations. For the vast majority of users,
