No moderators are going to take you up on that offer I'm afraid, I for one am no expert on weed. What are others posting on the forums? have you seen anyone else raising concerns? I would say if it smells chemically that could be an indication of it having been grown poorly and not flushed though before being cropped, often chemicals are added to the plant feed during growing to boost potency of the THC but those chemicals needs to be flushed afterwards which takes time. If the grower didn't do that the plant may have a nasty smell and be pretty grim to smoke. I am of course just speculating.
