A recent study has found that heavy intake of marijuana can damage the working of brain and can lower the learning capabilities of a person. Researchers of the study have further noted that those who indulge in the habit of drug abuse at an early stage have worse affect on their brains in their later part of life.

The study was conducted by a team of researchers from Melbourne's Murdoch Children Research Institute (MCRI), Melbourne University and Wollongong University. For the study, the researchers scanned the brains of 59 people. The participants of the study were said to be in the habit of drug abuse for at least 15 years.

The researchers further noted that the impact of the drug abuse can be significant over the development of the brain and in most cases, the changes are almost irreversible. It has been found that young children at the age of 10 and 11 fell into the traps of drug abuse.

Dr. Marc Seal of MCRI was reported of saying, "This is the first study to demonstrate the age at which regular cannabis use begins is a key factor in determining the severity of the brain damage".
