The rate at which the substance crosses the blood-brain barrier and triggers the reward pathway in your brain. A pioneering study revealing both positive and negative modulatory effects of beta-arrestin2 on THC tolerance. A decrease in aversion sensitivity, in simpler terms, means that an individual’s behavior is less likely to be influenced by undesirable outcomes. The new study shows, that the vaccine may also save lives during a drug overdose. In this instance, the idea is that the body will respond to the vaccine by quickly producing antibodies to prevent the opioids from accessing the brain.

Illicit drug use has been found to cause epigenetic changes in DNA methylation, as well as chromatin remodelling. The epigenetic state of chromatin may pose as a risk for the development of substance addictions. It has been found that emotional stressors, as well as social adversities may lead to an initial epigenetic response, which causes an alteration to the reward-signalling pathways. This change may predispose one to experience a positive response to drug use.

An action performed once as an experiment in a social situation can soon develop into a habit.

Kalivas’ group showed in that after extended withdrawal from chronic cocaine self-administration, cocaine-induced metaplasticity at the excitatory synapses in the NAc that impairs the ability of PFC stimulation to produce LTP or LTD in NAc MSNs. They also showed that N-acetylcysteine reverses cocaine-induced metaplasticity, allowing the induction of both LTP and LTD and that N-acetylcysteine decreases cocaine-relapse in a rodent model.

Naltrexone, for example, can’t be used until someone has fully detoxed from opioids. Taking NNaltrexone before the body has had a chance to detox can lead to very harsh and powerful withdrawal side effects. Researchhas found serotonin is another brain chemical that may play a role in addiction. Its possible role in impulsivity, can lead to impulsive drug-related decisions and the cycle of addiction, including the initial drug use, repeated use and relapse.
