In 1984 cannabis derivatives, in particular marijuana, hashish and liquid hashish, continued to be the most readily available drugs of abuse in Canada. Marijuana originating in Colombia decreased on the illicit marijuana market in Canada from an estimated 45 per cent in 1983 to 30 per cent in 1984, but it remained the largest source of marijuana supply. Marijuana originating in Thailand remained at approximately the same level (20 per cent) in 1984 as in 1983, while marijuana of Jamaican origin increased its share in the illicit market from 10 per cent in 1983 to 20 per cent in 1984. Approximately 10 per cent of marijuana on the illicit market originated in Canada, 10 per cent in Mexico, and 10 per cent in the United States of America. In 1984 an estimated 85 per cent of hashish on the illicit market in Canada originated in Lebanon (55 per cent in 1983), 10 per cent in India or Pakistan (31 per cent in 1983) and 5 per cent in Jamaica (2 per cent in 1983). Illicit shipments in tonnes of hashish originating in Lebanon made this the dominant source of supply of the drug. Liquid hashish originating in Jamaica shared 88 per cent of the illicit market of this drug in Canada during 1984, while 10 per cent of the drug originated in Lebanon and 2 per cent in Canada. In 1984 an estimated 40 per cent of smuggled marijuana entered the illicit market in Canada by air and approximately the same amount by sea, while 20 per cent was smuggled over land. During the same year, hashish was smuggled into Canada primarily by sea, while air accounted for 5 per cent and land for 1 per cent only. Liquid hashish, in contrast, entered Canada primarily by air, and only 9 per cent by land and 1 per cent by sea.
1984年，大麻衍生物，特别是大麻、哈希什和液体哈希什，仍然是加拿大最容易获得的滥用药物。原产于哥伦比亚的大麻在加拿大非法大麻市场上的占比从1983年估计的45%降至1984年的30%，但它仍是大麻供应的最大来源。原产于泰国的大麻在1984年与1983年大致保持在同一水平（20%），而原产于牙买加的大麻在非法市场中的份额从1983年的10%增至1984年的20%。非法市场上约10%的大麻原产于加拿大，10%原产于墨西哥，10%原产于美利坚合众国。1984年，加拿大非法市场上估计85%的哈希什原产于黎巴嫩（1983年为55%），10%原产于印度或巴基斯坦（1983年为31%），5%原产于牙买加（1983年为2%）。原产于黎巴嫩的非法哈希什运输量使其成为该药物的主要供应来源。1984年，原产于牙买加的液体哈希什在加拿大该药物非法市场中占88%，而10%的该药物原产于黎巴嫩，2%原产于加拿大。1984年，估计40%的走私大麻通过空运进入加拿大非法市场，海运进入的数量大致相同，而20%是通过陆路走私的。同年，哈希什主要通过海运走私进入加拿大，空运占5%，陆路仅占1%。相比之下，液体哈希什主要通过空运进入加拿大，通过陆路进入的仅占9%，通过海运进入的占1%。
