Will drinking 2-3 beers 6 times a week for a month show up on hair follicle test? if so for how long? how long do i need to abstain to get a clean test?

90 days: hair testing for drugs and alcohol can detect the by products of these substances for as long as 90 days. More importantly, drinking 2-3 beers 6 times a week indicates that you may have a substance abuse issue. Long term effects of drinking this much can include liver damage/failure, pancreatitis, ulcers/gastrointestinal problems, obesity, and heart disease in addition to the emotional toll.
