Cannabis (drug)

Cannabis (drug)
Cannabis is often consumed for its psychoactive and physiological effects, which can include heightened mood or euphoria, relaxation,[10] and an increase in appetite.[11] Unwanted side-effects can sometimes include a decrease in short-term memory, dry mouth, impaired motor skills, reddening of the eyes,[10] and feelings of paranoia or anxiety.[12] Effects Main short-term physical effects of cannabis A 2013 literature review said that exposure to marijuana had biologically-based physical, mental, behavioral and social health consequences and was "associated with diseases of the liver (particularly with co-existing hepatitis C), lungs, heart, and vasculature".[21] The medicinal value of cannabis is disputed. The American Society of Addiction Medicine dismisses the concept of medical cannabis because the plant fails to meet its standard requirements for approved medicines.

Caffeine Caffeine is a central nervous system (CNS) stimulant of the methylxanthine class.[10] It is the world's most widely consumed psychoactive drug. Unlike many other psychoactive substances, it is legal and unregulated in nearly all parts of the world. There are several known mechanisms of action to explain the effects of caffeine. The most prominent is that it reversibly blocks the action of adenosine on its receptor and consequently prevents the onset of drowsiness induced by adenosine.

Legality of cannabis The medicinal use of cannabis is legal in a number of countries, including Canada, the Czech Republic and Israel. While federal law in the United States bans all sale and possession of cannabis, enforcement varies widely at the state level and some states have established medicinal marijuana programs that contradict federal law—Colorado and Washington have repealed their laws prohibiting the recreational use of cannabis, and have instated a regulatory regime that is contrary to federal statutes.[6][7] Currently Bangladesh, North Korea, Czech Republic, Portugal, Uruguay, the Netherlands, and the United States (Washington and Colorado) have the least restrictive cannabis laws while China, Indonesia, Japan, Sweden, Turkey, France, Singapore, Malaysia, South Korea and the United Arab Emirates have the strictest cannabis laws. Worldwide, marijuana is the most popularly used illegal drug.[9] History[edit] Cannabis has been in use for thousands of years.

Cannabis foods Various cannabis foods on display in Amsterdam Nomenclature[edit] There are many different names and slang terms for the recipes. Prefixes such as edibles, hash, cannabis, weed, space, cosmic, freaky, magic, special, enhanced, medicated, fabricated, buffed, stimulated, stimmed, superskunk, spiked, evolved, fortified are added to the name of the food that they are prepared with: "hash cakes," "special brownies" etc. Ingredients and effects[edit] Tetrahydrocannabinol (THC) is generally considered to be the primary active substance in cannabis.

Cannabinoid receptor CB1 and CB2 structures. There are currently two known subtypes of cannabinoid receptors, termed CB1 and CB2.[5][6] The CB1 receptor is expressed mainly in the brain (central nervous system or "CNS"), but also in the lungs, liver and kidneys. The CB2 receptor is expressed mainly in the immune system and in hematopoietic cells.[7] Mounting evidence suggests that there are novel cannabinoid receptors[8] that is, non-CB1 and non-CB2, which are expressed in endothelial cells and in the CNS. In 2007, the binding of several cannabinoids to a G protein-coupled receptor (GPCR) in the brain was described.[9] The protein sequences of CB1 and CB2 receptors are about 44% similar.[10] When only the transmembrane regions of the receptors are considered, amino acid similarity between the two receptor subtypes is approximately 68%.[4] In addition, minor variations in each receptor have been identified.

Cocaine Cocaine (INN) (benzoylmethylecgonine, an ecgonine derivative) is a crystalline tropane alkaloid that is obtained from the leaves of the coca plant.[5] The name comes from "coca" and the alkaloid suffix "-ine", forming "cocaine". It is a stimulant, an appetite suppressant, and a nonspecific voltage gated sodium channel blocker, which in turn causes it to produce anaesthesia at low doses. Biologically, cocaine acts as a serotonin–norepinephrine–dopamine reuptake inhibitor, also known as a triple reuptake inhibitor (TRI). It is addictive due to its effect on the mesolimbic reward pathway.[6] It is markedly more dangerous than other CNS stimulants, including the entire amphetamine drug class,[7] at high doses due to its effect on sodium channels, as blockade of Nav1.5 can cause sudden cardiac death. Unlike most molecules, cocaine has pockets[clarification needed] with both high hydrophilic and lipophilic efficiency, violating the rule of hydrophilic-lipophilic balance.

Memory Overview of the forms and functions of memory in the sciences In psychology, memory is the process in which information is encoded, stored, and retrieved. Encoding allows information that is from the outside world to reach our senses in the forms of chemical and physical stimuli. In this first stage we must change the information so that we may put the memory into the encoding process.
