It’s slightly more lipophilic, not heavily so. The main draw of meth from a pharmacodynamic perspective is that it slows enzymatic degradation (you’re high longer). On a mg for mg basis dextroamphetamine is actually stronger than meth.
Tooth decay is caused by dry mouth and poor hygiene. The added methyl group doesn’t affect this aspect.





I’d love to get paid to test experimental drugs. So far it’s only cost me money.
