Cameron, the son of veteran Hollywood actor, Michael Douglas, has been released after about seven years behind bars.
The young actor was arrested by the Drug Enforcement Administration having found in possession of 0.5 pounds of methamphetamine.
Based on US laws, such act is sufficient enough to charge a felon to court, as it could be interpreted that such a person had an intent to distribute the substance.

According to Us Magazine, Cameron Douglas "was sentenced to five years in prison in April 2010, but his sentence was extended the following year when he pleaded guilty to smuggling heroin and other drugs into jail."
He was scheduled to be released in 2018, but fortunately got his freedom two years before his due date.
Following this, the actor plans to spend his time away from prison judiciously.
He reportedly wants to write a memoir about his time in incarceration and his battle against drug addiction.
