The Buddha outlines five types of trade that a lay disciple should avoid: trade in weapons, living beings, meat, intoxicants, and poisons.
“Pañcimā, bhikkhave, vaṇijjā upāsakena akaraṇīyā. Katamā pañca? Satthavaṇijjā, sattavaṇijjā, maṁsavaṇijjā, majjavaṇijjā, visavaṇijjā—imā kho, bhikkhave, pañca vaṇijjā upāsakena akaraṇīyā”ti.
“Bhikkhus, there are these five |trades::dealings [vaṇijjā]| that a lay disciple should not engage in. What five? |Trade in weapons::arms dealings [satthavaṇijjā]|, |trade in living beings::slave trade, human trade [sattavaṇijjā]|, |trade in meat::animal trade [maṁsavaṇijjā]|, |trade in intoxicants::drug trade [majjavaṇijjā]|, and |trade in poisons::dealing in deadly substances [visavaṇijjā]|. These, bhikkhus, are the five trades that should not be practiced by a lay disciple.”
