Responding to supplementaries, Social Justice and Empowerment Minister Thaawarchand Gehlot said Rs 21 crore worth of funds have been allocated for the survey.
He said the number of people turning up at de-addiction centres indicated that the number of addicts was increasing as also the fact that more and more people were being cured.
In his written submission, the minister said the last national survey on the extent, pattern and trend of drug abuse was carried out in 2000-01.
The survey covered only 40,697 males within the age group of 12-60 years. The survey did not provide state level data.
A rapid survey in Punjab and Manipur was also carried out in 2015, Gehlot said.
