(S)-6-phenyl-2,3,5,6-tetrahydroimidazo(2,1-b)(1,3)thiazole. Levamisole was originally used as an agent against threadworms (anthelmintic), but has not been used in human medicine since 2004 because of undesirable drug effects.
Forms of appearance:
Powder or tablets.
Levamisole is used as an extender because it both enhances and prolongs the effect of cocaine. In addition, levamisole has similar chemical properties and does not separate from cocaine when the hydrochloride is converted to base (similar melting point).
Vomiting, diarrhoea, allergic reactions (shortness of breath, skin rashes, swelling of the lips, tongue or face), disturbances of the nervous system (numbness up to unconsciousness). On the psychological level, blackouts, severe fatigue and articulation problems may occur.
The most dangerous side effects are aplastic anaemia, agranulocytosis and vasculitis. The former leads to a greatly reduced defence against serious infections due to a lack of white blood cells. Agranulocytosis is a severe reduction in granulocytes, a subgroup of white blood cells. Vasculitis leads to the death (necrosis) of skin areas due to the occlusion of small blood vessels.
The probability of developing agranulocytosis increases with the regularity of levamisole intake, irrespective of the dose taken.
Another risk is posed by the degradation of levamisole to Aminorex (amphetamine-like substance) in the human body; Aminorex had to be withdrawn from the market as an appetite suppressant because it led to pulmonary hypertension (= life-threatening pulmonary hypertension). This risk accumulates when Aminorex is taken repeatedly. Pulmonary hypertension does not occur acutely during use, but may only manifest itself after several months in the form of increasingly impaired physical performance, circulatory disorders and fatigue.
Symptoms such as chills, infections in the respiratory tract, anal region, throat, etc. may be associated with the intake of levamisole. These must be accompanied by a doctor and treated with antibiotics.
If possible, have your cocaine chemically analysed.
Refrain from mixed consumption, as unknown and unpleasant interactions may occur.
Regular consumption of Levamisole can weaken the immune system, resulting in a higher susceptibility to disease and inflammation.
Take regular breaks from cocaine use. Also to minimise the risks of Levamisole.
