types of drug:-

HEROIN

Heroin is an opioid or narcotic analgesic made from a sticky resin secreted by the opium poppy, Papaver somniferum. Produced by a chemical process, it results in a white, brown or pink powder or granules. The most common form of heroin seized in Australia is the purest form - a white powder that is easily dissolved and injected intravenously. Street heroin is often "cut" with additives making it difficult to establish the actual contents or purity of a street deal.

ALCOHOL

Pure alcohol is a colourless, tasteless liquid produced by fermentation, a process in which water and yeast act on sugars from a grain, vegetable or fruit. When discussed as a drug, "alcohol" becomes the collective term for a wide variety of alcoholic beverages. Most are commercially produced and contain a written indication of their alcoholic content on the packaging. Alcohol is the most widely used recreational drug in Australia and is responsible for a large proportion of drug-related health problems and deaths.

STEROIDS

Anabolic and androgenic steroids can be produced naturally or derived from synthetic sources. Commercially produced steroids can be placed into three groups - those produced for human consumption, those for veterinary use and those produced illegally. Steroids are used to increase muscle bulk and strength and to enable longer and harder athletic training sessions. Some users take steroids for cosmetic (body image) reasons.

AMPHETAMINES

Amphetamines are produced from an oil base but may be found in a number of forms. The most common is for the oil to be converted into a powder. The powder may be made into capsules or tablets. Methamphetamine may appear as rock-like crystals or as a liquid. Methamphetamine, although structurally similar to amphetamine, is more pure and longer lasting. Occasionally a very high purity gel or putty like substance can be produced. Amphetamine is often "cut" with adulterants such as sugar, glucose or ephedrine.
