Something is ravaging through the gay community, leaving death and misery in its wake, yet few are willing to talk about it. If I’d written that sentence a generation ago, I’d have been referring to the Aids crisis. But this time the enemy isn’t a virus, but a substance called ‘tina’ or ‘ice’. It is a methamphetamine – a stimulant drug that is either smoked or injected into the veins. Tina is also called crystal meth, made famous by the Netflix series Breaking Bad. It causes a rapid increase in dopamine, serotonin and noradrenaline, which leads to euphoria, alertness, energy and self-confidence. It also triggers an almost insatiable increase in libido. It’s easy to see the appeal. But the downsides are horrific.
