This is the most definitive sign that your child is abusing drugs. The possession of items such as weight scales, smoking pipes, butane torches, bongs, cigarette lighters, small porcelain bowls, hypodermic needles, balloons, and vials are all indicative of drug use. The Partnership to End Addiction recommends doing the following if you suspect your teen is abusing drugs: Use your nose – if your teen has been drinking or smoking, the smell will likely be on their breath, on clothing, and in their hair Look them in the eyes – oftentimes, signs of drug or alcohol use can be seen in the eyes, including: Eyes will be red and heavy-lidded with constricted pupils if they’ve been using marijuana Pupils will be dilated and they may have trouble focusing if they’ve been drinking alcohol Their face and/or cheeks may be red or flushed if they’ve been drinking Search their space – if drug use is a concern, the limits you set with your teen shouldn’t have to stop at the front door or at their bedroom door. Communicate why you intend to search their space and that it’s out of concern for their health and safety, and check places like: Drawers small boxes or cases under the bed in a plant inside books under loose floorboards inside over-the-counter medicine containers inside wrappers or other containers, such as a fake soda can
