By definition, sugar is much closer to a drug than it is to food, particularly for those who. 8 Crack, cocaine, and SUGAR cause their high by affecting dopamine.

Purer forms of crack resemble a hard brittle plastic, in crystalline form (snaps when broken). A crack rock acts as a (see: ), numbing the tongue or mouth only where directly placed. Purer forms of crack will sink in water or melt at the edges when near a flame (crack vaporizes at 90 °C, 194 °F). Crack cocaine as sold on the streets may be or 'cut' with other substances mimicking the appearance of crack cocaine to increase bulk. Use of toxic adulterants such as has been documented.

A close up of the 'cooking' process that creates crack. (NaHCO 3, common baking soda) is a base used in preparation of crack, although other may substitute for it.

The net reaction when using sodium bicarbonate is Coc-H +Cl − + NaHCO 3 → Coc + H 2O + CO 2 + NaCl With: Coc-H +Cl − + NH 4HCO 3 → Coc + + CO 2 + H 2O With: 2(Coc-H +Cl −) + (NH 4) 2CO 3 → 2 Coc + 2 NH 4Cl + CO 2 + H 2O Crack 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. This process is frequently done with baking soda (sodium bicarbonate), water, and a spoon. Once mixed and heated, the bicarbonate reacts with the hydrochloride of the powder cocaine, forming free base cocaine and (H 2CO 3) in a reversible acid-base reaction.

The heating accelerates the degradation of carbonic acid into (CO 2) and water. Loss of CO 2 prevents the reaction from reversing back to cocaine hydrochloride. Free base cocaine separates as an oily layer, floating on the top of the now leftover aqueous phase. It is at this point that the oil is picked up rapidly, usually with a pin or long thin object. 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.

Crack vaporizes near temperature 90 °C (194 °F), much lower than the cocaine hydrochloride melting point of 190 °C (374 °F). 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. Crack cocaine can also be injected intravenously with the same effect as powder 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. Recreational use.

A woman smoking crack cocaine. Crack cocaine is commonly used as a recreational drug.

Effects of crack cocaine include, supreme confidence, loss of appetite,, alertness, increased energy, a craving for more cocaine, and potential paranoia (ending after use).
