I agree about the meth teeth and they dont happen in 3-4 years. Those teeth take 5-10 years to degrade to the extent that HBs teeth are in, assuming its not a doctored photo.
Meth mouth is also more severe, as in HBs case, in users who inject the drug, rather than smoke or ingest it. That would seem to suggest that HB was a pretty hardcore user for a long time.
Who is HB?
