Cannabis
Cannabis is illegal in Laos and there is no legal way to buy it, however relaxed the country's reputation. Laos's own Penal Code (No. 26/NA, 17 May 2017) draws the lines by weight: holding under 5 g of marijuana for your own consumption is not punished with prison - the Code treats that person as a victim, to be treated or sent for treatment - while 5 to 10 g for consumption is 6 months to 2 years in prison plus a fine. Anything held "for trading" is trafficking, from 6 months to 3 years for under 5 kg of dry marijuana up to 5 to 10 years above 10 kg, and running a place that serves cannabis is a separate offence. Hashish and THC concentrates are punished far harder than leaf: the bands start at 0.3 g and reach life imprisonment above 500 g.
Penal Code of the Lao PDR No. 26/NA, adopted by the National Assembly on 17 May 2017 and promulgated by Presidential Decree No. 118/PO of 26 June 2017; figures taken from the English version published by the Lao Official Gazette. Art. 320 (consumption or possession for consumption): marijuana under 5 g - the person is regarded as a victim and is treated or sent for treatment; 5 to 10 g of dry marijuana - 6 months to 2 years plus a fine of 5,000,000 to 20,000,000 kip; providing a service for consuming marijuana - 3 months to 5 years plus 1,000,000 to 5,000,000 kip. Art. 318 (trading): under 5 kg of dry marijuana - 6 months to 3 years plus 1,000,000 to 5,000,000 kip; 5 to 10 kg - 3 to 7 years plus 5,000,000 to 20,000,000 kip; over 10 kg, or on a regular basis or as an organised group - 5 to 10 years plus 20,000,000 to 50,000,000 kip; marijuana seeds over 10 g - 1 to 3 years. Tetrahydrocannabinol, hashish and THC derivatives by net weight: 0.3 to 50 g - 2 to 4 years; 50 to 100 g - 5 to 7 years; 100 to 200 g - 10 to 14 years; 200 to 500 g - 15 to 20 years; over 500 g - life imprisonment plus 100,000,000 to 200,000,000 kip and confiscation of assets. The Code reserves the death penalty for the heaviest offences involving other drug classes; for marijuana the top band in art. 318 is life imprisonment.

Alcohol
Laos authorities have issued an order prohibiting the sale and consumption of Tiger Vodka and Tiger Whisky on health-risk grounds - two named brands you may still be offered in bars. Alcohol is otherwise legal in Laos, but methanol poisoning has caused deaths and serious illness there, including from drinks bought in licensed bars, shops and hotels in tourist areas, and methanol cannot be detected by taste or smell.

Vaping / E-cigs
Vapes are illegal in Laos, and so are heated tobacco products and shisha (water-pipe tobacco). The ban is not limited to selling: possessing, using, importing, buying, selling or exporting any of them is an offence, so simply arriving with a vape in your bag breaks the law.
You could be fined or imprisoned for possessing, using, importing, selling, purchasing or exporting vapes, heated tobacco or shisha.
