The legal status of anabolic steroids varies from country to country: some have stricter controls on their use or prescription than others though in many countries they are not illegal. In the U.S., anabolic steroids are currently listed as Schedule III controlled substances under the Controlled Substances Act, which makes the first offense simple possession of such substances without a prescription a federal crime punishable by up to one year in prison, and the unlawful distribution or possession with intent to distribute anabolic steroids punishable as a first offense by up to five years in prison (to be increased to ten years, effective on or about April 13, 2009).[100] In Canada, anabolic steroids and their derivatives are part of the Controlled drugs and substances act and are Schedule IV substances, meaning that it is illegal to obtain or sell them without a prescription; however, possession is not punishable, a consequence reserved for schedule I, II or III substances. Those guilty of buying or selling anabolic steroids in Canada can be imprisoned for up to 18 months. Import and export also carry similar penalties.[101] Anabolic steroids are also illegal without prescription in Australia,[102] Argentina, Brazil and Portugal,[103] and are listed as Class C Controlled Drugs in the United Kingdom. On the other hand, anabolic steroids are readily available without a prescription in some countries such as Mexico and Thailand.
