The short-term physiological effects of cocaine include constricted blood vessels, dilated pupils, and increased temperature, heart rate, and blood pressure. Main physiological effects of crack cocaine However, whereas powder cocaine dissolves in water, crack must be dissolved in an acidic solution such as lemon juice or white vinegar, a process that effectively reverses the original conversion of powder cocaine to crack. Crack cocaine can also be injected intravenously with the same effect as powder cocaine. Whereas cocaine hydrochloride cannot be smoked (burns with no effect), crack cocaine when smoked allows for quick absorption into the blood stream, and reaches the brain in 8 seconds. This pulls the oil up and spins it, allowing air to set and dry the oil, and allows the maker to roll the oil into the rock-like shape.Ĭrack vaporizes near temperature 90 ☌ (194 ☏), much lower than the cocaine hydrochloride melting point of 190 ☌ (374 ☏). It is at this point that the oil is picked up rapidly, usually with a pin or long thin object.

Free base cocaine separates as an oily layer, floating on the top of the now leftover aqueous phase. Loss of CO 2 prevents the reaction from reversing back to cocaine hydrochloride. The heating accelerates the degradation of carbonic acid into carbon dioxide (CO 2) and water. Once mixed and heated, the bicarbonate reacts with the hydrochloride of the powder cocaine, forming free base cocaine and carbonic acid (H 2CO 3) in a reversible acid-base reaction. This process is frequently done with baking soda (sodium bicarbonate), water, and a spoon. With Ammonium carbonate: 2(Coc-H +Cl −) + (NH 4) 2CO 3 → 2 Coc + 2 NH 4Cl + CO 2 + H 2OĬrack cocaine is frequently purchased already in rock form, although it is not uncommon for some users to 'wash up' or 'cook' powder cocaine into crack themselves. With Ammonium bicarbonate: Coc-H +Cl − + NH 4HCO 3 → Coc + NH 4Cl + CO 2 + H 2O The net reaction when using sodium bicarbonate is Coc-H +Cl − + NaHCO 3 → Coc + H 2O + CO 2 + NaCl Sodium bicarbonate (NaHCO 3, common baking soda) is a base used in preparation of crack, although other weak bases may substitute for it. SynthesisĪ close up of the 'cooking' process that creates crack. Use of toxic adulterants such as levamisole has been documented. Ĭrack cocaine as sold on the streets may be adulterated or 'cut' with other substances mimicking the appearance of crack cocaine to increase bulk. Purer forms of crack will sink in water or melt at the edges when near a flame (crack vaporizes at 90 ☌, 194 ☏). A crack rock acts as a local anesthetic (see: cocaine), numbing the tongue or mouth only where directly placed. Purer forms of crack resemble a hard brittle plastic, in crystalline form (snaps when broken). In purer forms, crack rocks appear as off-white nuggets with jagged edges, with a slightly higher density than candle wax. Crack first saw widespread use as a recreational drug in primarily impoverishedinner city neighborhoods in New York, Philadelphia, Baltimore, Washington, D.C., Los Angeles, and Miami in late 19 its rapid increase in use and availability is sometimes termed as the 'crack epidemic'.

The Manual of Adolescent Substance Abuse Treatment calls it the most addictive form of cocaine. Crack offers a short but intense high to smokers. Crack cocaine, also known simply as crack or rock, is a free base form of cocaine that can be smoked.
