The increasing exposure to the drug decreases the amount of dopamine that the brain naturally releases, which can permanently affect the neural networks. When users think about crack, the new neural pathways that crack has formed invoke positive emotions, as crack becomes more and more associated with intense euphoria. Crack use leads to the formation of new neural networks that are formed by large amounts of dopamine, which also contributes to the addictive nature of the drug. If someone does something correctly, the brain releases a small amount of the drug to reward and encourage similar behaviors. It is the intense desire to recapture the initial high that is so addictive for many users.ĭopamine is used in the formation of neural networks, or ways that we think. A typical response among users is to have another hit of the drug, however, the levels of dopamine in the brain take a long time to replenish themselves, and each hit taken in rapid succession leads to increasingly less intense highs. The high usually lasts around 15 minutes, after that time dopamine levels in the brain plummet, leaving the user feeling depressed and low. Its main effect is to release a large amount of dopamine, a brain chemical inducing feelings of euphoria. The health effects of these are generally mild compared to the health effects of the drug, but a number of highly toxic substances may also be used when available, with serious consequences resulting from consumption.Ĭocaine is a substance that affects the brain chemistry of the user. For reasons of salability, the person reducing the purity will obviously prefer to do so with a substance that does not excessively alter the color or odor, and a bulked batch will commonly contain some level of acetone and bicarbonate. The other 60%-90% can be made up of almost any available substance the chemists and/or dealers have chosen to use. Coc-H +Cl – + NaHCO 3 → Coc + H 2O + CO 2 + NaClĬrack cocaine usually contains 40% cocaine or less, depending on the degree to which it has been bulked out with other substances.
