The most famous in that family seems to be meth(amphetamine)
It's a huuuuuge family of substances though, particularly if you go one step more generic and start with Phenylethylamine as the backbone (amphetamine is a shortening of alpha-methyl-phenethylamine), the family includes hallucinogens like mescaline, empathogens like MDMA and its close cousins, the whole 2C family, the cathinones and their derivatives ('mephedrone' had a cultural moment 10-15 years back). And some real nasties like PMA, PMMA and bromo-Dragonfly.
