There have been a number of reports from users in the Portsmouth area that extremely dangerous batches of Herion have been in circulation.
Portsmouth User Self Help (PUSH) have had reports of extreme adverse effects such as, memory loss and no recollection of events or happenings over a number of days and even death.
Some signs to look out for are a purple colour to the heroin when ‘cooked up’ and also a grey tinge to the heroin when still in powder form.
