Active substances: Cathinone, cathine and others.
Effects: Stimulating, appeases the hunger, slightly euphoriant, after some hours sedation takes place. The kath inebriation ends in a depressive mood.
Side Effects: None are known from moderate use. Frequent regular use can lead to impotence, apathy and strong addiction.
Suppliers: Legally fresh leaves can be bought only in GB und NL, plants and seeds are available in the ethnobotanical trade.
Remarks: The main constituent of kath, cathinone, is since 1986 listed in the German BtMG (narcotics act). The kath plant itself is not listed in the BtMG; the possession because of botanical interest is hence not prohibited, if “Abuse for inebriation purposes is [not] intended”. Most countries have similar regulations.
