effects/cutting down

[ivgotmyheadintheclouds]

swim started taking speed on a regular basis (5-6 times a week) about 12 months ago and has just realised how much she is using. It started as 5g a week but is now an ounce+ a week, swim now relys on it as she has 2 jobs and works allot of hours. Swim is worried about the amount she is using (and the money she is spending!) and is wondering about the long term effects her usage will cause. She also would like advice on cutting down and any other advice anyone has.
