The study - "Women Who Use Drugs in Northeast India" - noted, "A household survey in the state found that 2.1 per cent of females were opium users" and that "a majority of them were introduced to opium by their husbands after marriage".
Among 100 persons, who were surveyed, 6.4 per cent had taken drugs at least once (just ahead of Tripura's 1.1 per cent), the study found.
A higher percentage of drug consumption was found prevalent amongst users in Manipur (28.2 per cent), Mizoram (17.4 per cent), Nagaland (14.9 per cent), Meghalaya (12.1 per cent), Assam (10.2 per cent) and Sikkim (9.8 per cent).
This is the first comprehensive study of women who use drugs across all the eight states of the Northeast.
The study said "substance use among women is associated with early initiation to sex, sexual abuse, greater number of sexual partners, exchange of money for sex, and infrequent use of condoms with sexual partners".
It noted that among more than half of the women drug users in Arunachal Pradesh, the prime source of income is through selling drugs or sex.
Concerns were raised regarding the fact that in low HIV burden states, a significant proportion (57 per cent) of women begins to inject drugs without transitioning from non-injecting.
It also stated that women in these states "who use drugs exhibit greater frequency of paid sex as well as sex in exchange for drugs".
