sniffling all of the time, going to the bathroom all of the time to take a snort, some users may have a real long fingernail usually the pinky to use instead of a straw or tuter, or dollar bill, white powder visible near the nostrils, causes dry mouth so they may have white saliva in the corners of their mouth, may carry a razor blade to cut a rock, white powder left on mirror, people coming and going all of the time if they are selling it. Stays up all night.  Behaviors  could be not going home or going around family, broke, may sell items out of the home to buy more, sexual appetite, i'm sure there is more but this is all i could think of.
