Ruby is a drug found in the Sunset Isles. It is similar in appearance and size to rock salt, however it has a deep red colour (hence the name Ruby).

Ruby is generally mixed with water and drunk and it has a sweet taste. Some of the more addicted users will eat the crystals directly. It is said to have a faint taste of cherries.

The immediate side effects of Ruby are:

Dilated pupils, excessive sweating, rapid breathing and tremors

These generally last for 30 minutes to an hour, after which the user slips into a state of deep relaxtion. Whilst in this state, their cognitive ability is severely hindered and users cannot perform or comprehend the simplest of tasks.

The withdrawal symptoms of Ruby are characterised by an extended period in which the user suffers from the immediate side effects.
