some info for you and your g/f
Ephedrine is a drug derived from plants of the genus Ephedra, most commonly used to prevent mild or moderate attacks of bronchial asthma. Unlike epinephrine, to which it is chemically similar, ephedrine is slow to take effect and of mild potency and long duration. A bronchodilator and decongestant, ephedrine is used to relieve nasal congestion originating from allergic conditions, e.g., hay fever, or from bacterial or viral infection of the upper respiratory tract. It is also used to raise blood pressure. Ephedrine is the active constituent of ma huang, a desert herb used medically in China for thousands of years. It is used in the production of methamphetamine (see amphetamine desc.) and is also the active ingredient in ephedra, or herbal ecstasy. Ephedra may cause such side effects as insomnia, restlessness, euphoria, palpitations, and high blood pressure; there have been reports of deaths associated with its use as a "natural recreational drug.
Amphetamine is any one of a group of drugs that are powerful central nervous system stimulants. Amphetamines have stimulating effects opposite to the effects of depressants such as alcohol, narcotics, and barbiturates. They raise the blood pressure by causing the body to release epinephrine, postpone the need for sleep, and can reverse, partially and temporarily, the effects of fatigue. Amphetamines enhance mental alertness and the ability to concentrate, and also cause wakefulness, euphoria, and talkativeness. Benzedrine is the trade name for the drug amphetamine; dextroamphetamine is marketed as Dexedrine. Methamphetamine, a potent stimulant marketed as Desoxyn, is the most rapidly acting amphetamine.
