A new study on drug use in Australian Aboriginal communities had found that restrictions on alcohol and petrol have led to an increased use of marijuana.
The 5-year study period involved the researchers in observation, and structured and unstructured interviews with young aboriginal people and adult community members.
The study highlights the importance of looking at indigenous substance misuse in the total context of indigenous poverty, poor health and lack of opportunities.

To put the problem into perspective, Australian national statistics show that marijuana use is common in Australia with at least 11% of the urban non-indigenous population using the drug - when it comes to the indigenous population this number doubles to 22%. It is also suspected that the rates of marijuana use may be much higher in remote indigenous communities throughout the Northern Territory.

This is significant becuase if they choose to ban alcohol in the united states this is what could potenitally happen.
