Marijuana is the most frequently used illegal drug in the U.S. Before five years, increasing rates of adult and youth marijuana use in the U.S. has been linked to the comprehensive understanding that marijuana is a comparatively low-hazard “recreational” drug and doesn’t lead to addiction. A recent 2013 national Gallup poll reported that 58% of Americans now support legalization of marijuana. Colorado and Washington have lately passed such laws, legalizing the sale of “recreational” marijuana and several other states are considering similar laws. In light of the national impetus that is growing, it is essential for people to get access to accurate scientific information and be notified of present research findings about advantages and the health hazards of marijuana and the public health significance of increasing accessibility and usage of marijuana.
Research suggests that people have a reduced danger to become hooked in comparison to those that use frequently and who sometimes use medical marijuana may endure fewer negative impacts. Routine use over long periods may cause changes in the brain and behaviour similar to other drugs that are addictive and may lead to addiction. Tetra hydro cannabinol (THC) in smoked marijuana enters the bloodstream and arrives in the brain almost immediately, inducing an individual to feel euphoric or “high” by activating the brain’s benefit or pleasure center to release dopamine in exactly the same manner that a number of other drugs do. Research demonstrates about 1 in 11 (9%) individuals using marijuana will end up dependent on it. The danger increases in people who begin smoking marijuana as teens to 1 in 6. People who become addicted to marijuana have trouble controlling their use, even when cause issues within their own lives and marijuana starts to interfere with. Long-Term, more heavy marijuana drug users frequently experience outward indications of cannabis withdrawal including increased stress, craving, irritability and sleep conditions that may make it almost impossible to give up. Continued use and withdrawal despite negative societal, personal, legal or medical effects are hallmarks of dependency and addiction.
The severe effects or “high” from THC usually last 1 to 3 hours and cause impaired focus and decision making and slowed reaction time, usually accompanied by poorer coordination and equilibrium. Studies demonstrate that marijuana use interferes with a man’s power to form new memories, information processing, along with learning.
