What is marijuana?
Marijuana wrapped in a paper.
Marijuana — also known as cannabis,marijuana, plant, grass, bud, ganja, MaryJane, and a large range of other slang terms — is a greenish-gray mixture of cannabis sativa's dried flowers. In hand-rolled cigarettes or cigars, some people smoke marijuana; in pipes ,( water pipes sometimes called bongs), or in blunts(marijuana rolling in cigar wraps). Marijuana may also be used to brew tea and is frequently mixed into foods(edibles) such as brownies , cookies, or sweets, especially when sold or consumed for medicinal purposes. Vaporizers are also widely used for marijuana used.
Stronger types of marijuana include sinsemilla (from specially tended female plants) and concentrated resins that contain high concentrations of the active ingredients of marijuana, including honey like hash oil, waxy budder, and hard amber smash. These resins are becoming increasingly common among those who use them both for recreational and medical purposes.
What effect does marijuana have ?
Once marijuana is smoked, the plant's THC and other chemicals migrate from the lungs into the bloodstream, which immediately brings them to the brain and the entire body.
The person starts experiencing effects almost instantly. Many people feel a good feeling of calm and euphoria. Certain common effects that can vary significantly between different individuals include increased sensory perception (e.g., brighter colours), laughter, altered perception of time, and increased appetite.
If marijuana is ingested in foods or drinks, these effects are somewhat delayed generally occurring after 30 minutes to 1hour — because the substance has to pass through the digestive system first.
Eating or consuming marijuana in the bloodstream contains far less THC than smoking an equal volume of the product.
People can unintentionally consume more THC than they plan to, because of the delayed effects. People that have taken large doses of marijuana can experience an acute syndrome that involves hallucinations ,delusions, and a lack of personal identity meaning. Such unpleasant yet acute reactions are distinct from long-lasting psychiatric disorders, such asschizophrenia, which may be associated with drug use in vulnerable people.
Pleasant marijuana encounters are by no means common. Some people feel anxiety, apprehension, mistrust or panic,rather than relaxation and euphoria.
These effects are more likely when an individual takes too much, marijuana has an unexpectedly high potency or the person is inexperienced.
While detectable amounts of THC may remain in the body for days or even weeks after use, the noticeable effects of smoked marijuana generally last from 1to 3 hours, while those of marijuana consumed in food or drink may last for many hours.
Effects of marijuana on driving
Marijuana substantially impairs judgment, motor control, and reaction speed and studies have found a clear correlation between blood THC concentration and impaired driving capacity.
Marijuana is the most popular illegal substance found in the blood of driver's involved in car accidents including fatal ones.
Two big European studies found that drivers with THC in their blood were nearly twice as likely to be guilty of a fatal accident as drivers without alcohol or drugs.
Two big European studies showed that drivers with THC in their blood were almost twice as likely as drivers who had not used drugs or alcohol to be guilty of a fatal accident. Nevertheless, the role of marijuana in accidents is still uncertain as it can be found in body fluids for days or even weeks after ingestion and as it is often mixed with alcohol by humans.
Its beneficial effects as a drug
For decades, the possible medicinal effects of marijuana and its residents have been the focus of study and intense discussion.
For different forms THC itselfhas proven medicinal benefits.
The US Food and Drug Administration (FDA ) has approved medicinal products based on THC,
Dronabinol (Marinol ®) and nabilone(Cesamet ®), administered in the form of a tablet to relieve nausea in patients undergoing cancer chemotherapy and to improve appetite in patients with AIDS-related wasting syndrome.
Additionally, several other medicationsbased on marijuana have been approved are undergoing clinical trials.
Nabiximols (Sativex ®), a mouth spray currently available in the UK, Canada and several European countries for the treatment of spasticity and neuropathicpain that may accompany multiple sclerosis, combines THC with another marijuana-based chemicals called cannabidiol (CB)
A CBD-based liquid medication called Epidiolex ® was also approved by the FDA to treat two forms of severe childhood epilepsy, Dravet syndrome and Lennox-Gastaut syndrome. It is administered to patients in a stable dosage form and via a reproducible delivery route to ensure patients receive the benefits anticipated. CBD lacks the rewarding THC properties. There are many barriers to the production of medicines from botanicals such as marijuana plant.
Botanicals may contain hundreds of unknown, active chemicals, and a product with accurate and consistent doses of these chemicals can be difficult to develop.
The use of marijuana as a medicine also poses other issues such as the adverse health effects of smoking and cognitive impairment caused by THC.
Nonetheless,a increasing number of states have approved marijuana dispensation or its extracts to people with a variety of medical conditions. An important problem with "legal marijuana" is that people with health and age-related vulnerabilities—such as older adults or people with cancer,AIDS, cardiovascular disease, multiple sclerosis or other neuro degenerative diseases—are little understood about the long-term effects of its usage.
More study would be required to determine if individuals whose health has been affected by illness or their care (e.g.,chemotherapy) are at increased risk of marijuana use adverse health outcomes.
