How can new amendment to steroid law influence on health of steroid-using athletes?

British people are not allowed to purchase steroids at online pharmacies. Importation of steroids into the UK is considered to be criminal under a new amendment to the steroid law. Those who live in the UK and import steroids into the country are sanctioned by authorities. But Britons may freely purchase, possess and use steroids.
According to the “personal custody”, those that came to London for the Olympics were allowed to import steroids for self-administration. It was not considered to be illicit under British laws. Nevertheless, those that live inside the UK don’t have any right to buy steroids via internet and import them from other countries to the UK.
Earlier British citizens were allowed to acquire steroids from outside the country. The amendment was provided by the Advisory Council on the Misuse of Drugs (ACMD) in order to protect health of those that take steroids. But could the amendment do it?
A lot of underground labs produce anabolic steroids inside the UK. They prosper because of the amendment. But it is necessary to take into account that a lot of underground labs manufacture fake steroids. Thus, British citizens have to get steroids of low quality because it is banned to import steroids that are produced outside the country by safe pharmaceutical companies.
Authorities warned Needle-Syringe Program (NSP) workers that they would have to work more. It was noted that the amendment would raise the number of steroid users.
In fact, the amendment is likely to have negative influence on health of steroid users. Steroid-using sportspeople and bodybuilders may get dangerous adverse consequences because they switch from quality steroids manufactured by trustworthy pharmaceutical companies to worse products produced by underground labs located in the UK.
