There isn't any research data I'm aware of as far as consumption and toxicity, so caution is advised.
Generally, though, the main drawback is that it's extremely moreish and people tend to take a lot more than they initially intended, which could potentially lead to immediate issues inherent to introducing too much of any chemical into your body at once. I'd say if you bought a gram from one of the UK websites, don't go about doing the whole gram yourself in one night... which from what I read... is deceptively easy.
