Searched DDs room and found Robitussin and a glucomannan and chromium supplement. I understand robitussin can be used in high doses to induce hallucinations, and the supplement seems to be for weight loss /constipation. Does anyone see anything else sinister in the combination? Are there any other things I need to look for? Luckily it doesn't look like much of either has been used but I am very worried! DD is 18 but young for her age. Going to uni in September, wondering how safe she'll be.
