<p>Do you mean me? Yes, have a brain, and while I have never had to take psychotropic, for my mental health I do study and prescribe them for a living. Perhaps I should have included more from the link which goes on to say…</p>
<p>Speed is the most popular name for amphetamine, which is a chemical compound that acts as a central nervous system stimulant. Its chemical structure closely resembles the body’s own chemical transmitter norepinephrine, which plays an important role in the fight-or-flight response to stress and excitement</p>
<p>There are three main pharmaceutical classes of amphetamine (the common brand names are in brackets): laevo or dl-amphetamine (Benzedrine), dextroamphetamine (Dexedrine) and methylamphetamine (Methedrine). The latter is also known as crystal meth and, weight-for-weight, is the most potent of the three.</p>
<p>The most common street speed is amphetamine sulphate, which contains equal amounts of laevo-amphetamine and dextroamphetamine. It comes as a grey, dirty-white or pinkish powder which is snorted, rubbed on the gums, dissolved in liquid for injection or drinking, or swallowed in pill form. A ‘speedbomb’ consists of speed wrapped in Rizlas, which is then swallowed.</p>
<p>I thought this was a useful response to the OP’s question. My apologies if I offended you. You have reminded me it is always risky to give and receive medical information/advice on a forum. How is the studying going?</p>
