Addiction And Dependency
- Regular use often builds a tolerance, requiring larger amounts to
receive the same effect
- It is possible to become psychologically dependant where other aspects
of the users life is neglected
- Psychological withdrawals can result in a craving for cannabis use
- Whether physical addiction is possible is debatable but those who
are dependent on cannabis can certainly display physical withdrawal
symptoms such as sweating, upset stomaches and in more severe cases,
chills. Any reports of physical withdrawls suggest that they are far
less severe then withdrawls from drugs such as heroin.
- Other withdrawal symptoms can include sleep disturbances, nervousness,
irritability and anxiety.
Overdose And Death
There have been no reported deaths from cannabis. The dose of cannabis
considered legal to human beings is roughly a third of a person’s
body weight. This is a very large amount of cannabis and ingesting this
amount is highly unlikely.
