LSD

LSD is the abbreviation for Lysergic Acid Diethylamide - a powerful mind-expanding drug which imbues users with numerous superhuman abilities, the most remarkable of which is the power of flight, but which also includes telepathy, visions, telekinesis, reading the future... and many, many more.

Despite these remarkable properties LSD is surprisingly cheap to buy, with a street price of around £3.00 ($5.00) per tab.

But since you're a mate I can do you ten for 25 quid.
