Moreover, it causes the constriction of blood vessels and is known to suppress appetite, though precisely how does this is not yet fully understood.ĭuring detox, withdrawal can be monitored and managed by medical professionals for the safety and comfort of the withdrawing addict.
Ĭocaine block sodium channels in the central nervous system, which obstructs the transfer of information relating to pain, thus making it an effective local anaesthetic. Serotonin is a chemical in the brain known to contribute to feelings of happiness and well-being. This creates crack’s euphoric effect, as well as making the consumption of the drug a rewarding experience in terms of the mechanism by which addiction develops.Ĭocaine is also known to affect some serotonin receptors, although how exactly this takes place is unclear. Most prominently, cocaine binds to dopamine transporters in the brain which prevent them from performing their dopamine reuptake function, meaning that dopamine accumulates in greater and greater quantities in the synaptic cleft. There are also concerns that smoking crack whilst pregnant or breastfeeding can damage a foetus or infant, though the precise nature and severity of the danger is not particularly well-established.Ĭrack impacts upon the brain in various ways.
Longer-term crack use can lead to an array of potentially significant physical and mental health issues including respiratory and cardiovascular problems, damage to organs including the liver, psychosis and delusional parasitosis, as well as to addiction. In some cases, sudden death from cardiac arrest, seizures or respiratory arrest can result even on the first instance of crack use. In the short term, the physiological effects of smoking crack include increased heart rate, temperature and blood pressure, constricted blood vessels and dilated pupils. This may last between five and fifteen minutes, after which the sensation will very rapidly dissipate, typically leaving users feeling intense cravings for more to repeat the experience and to stave off the resultant mood crash. Upon smoking crack, users will almost immediately feel an intensely euphoric and pleasurable high, typically accompanied by feelings of extreme alertness, confidence, hyperactivity and excitability and, often, by an upsurge in sexual desire. However, users can become profoundly psychologically dependent, with the quest to repeat the experience of the crack cocaine high coming to dominate their daily lives at huge and potentially devastating expense.
This is when the individual in question becomes psychologically reliant upon the repeated experience of consuming a substance and experiencing its effects psychological symptoms can manifest in instances of withdrawal.Ĭrack cocaine is not usually considered to have a high physical dependence liability. When this happens, physical withdrawal symptomsare likely to present.However, psychological dependence may also develop. the affected individual becomes physiologically reliant upon the substance. “Dependence” is frequently taken to mean physical dependence, i.e. Withdrawal symptoms may manifest when the substance becomes suddenly absent (is withdrawn) from the system. However, this did not, of course, mean that crack did not also find many takers within other ethnic groups.ĭependence is a phenomenon whereby the system of someone consuming a substance regularly over time becomes reliant upon the presence of that substance in order to function normally. From the start of what became known as the “crack epidemic”, there was a pronounced racial element to the public perception of crack use, with it being considered a predominantly “black” drug thanks to the overrepresentation of African-Americans in poorer neighbourhoods. Partly because of its affordability, crack became associated very early on with more disadvantaged neighbourhoods and users from lower socio-economic backgrounds. Their solution was crack cocaine, a smokable version of cocaine which, despite being made available at a lower cost than traditional cocaine, proved incredibly profitable thanks to the huge demand it immediately created amongst users.Ĭrack first appeared in the USA in 1981 and very rapidly penetrated urban centres across the country. This left suppliers searching for ways in which to increase the rate of cocaine consumption amongst users, and thus boost profits back up towards desired levels. The history of crack began in the late 1970s when a glut of cocaine on the US market caused prices to drop by up to 80% in many major markets.
