Laced

recently bought dmt from somebody who had previously sold to my friend. The dmt has Little Rock’s in it that sort of look like bath salts. It did have the right color. Smoked 2 points and felt a slight head high. Not only was it a gram over what it was supposed to it didn’t smell right and bubbles up black in the banger. Was this laced with bath alts or is it even dmt?
