Tetrapharmakos

(τετραφάρμακος), or "the four-part cure," is the Greek philosopher Epicurus' (341 BC, Samos – 270 BC, Athens) remedy for leading the happiest possible life. The "tetrapharmakos" was originally a compound of four drugs (wax, tallow, pitch and resin); the word has been used metaphorically by Epicurus and his disciples to refer to the four remedies for healing the soul.
Tetrapharmakos, the four-part cure;

Don't fear God,
Don't worry about death;
What is good is easy to get, and
What is terrible is easy to endure

καὶ τἀγαθὸν μὲν εὔκτητον,
τὸ δὲ δεινὸν εὐκαρτέρητον

Tetrahydrocannabinol
