Chop-chop is legal in Australia because we have choice as to the ripeness of the plant / plants we use .
The blue box indicates that the plant is not dead yet but has achieved full ripeness and is satisfying and has a cooling effect on the user .
The red box indicates full ripeness and death of the plant in the ground and has a mild heating and " nutritional " effect on the user .
Healthy humans can smoke either of these colours with the proviso that the environment that the user is in has recourse for the temperature / comfort effects . In extreme environments where life might be at risk the user should exercise caution . In habits of use there is rebound / " oppositional process theory " and spirituality to account for when considering your choice .
It is good to have consideration for what you are smoking ...
In Australia and most civilized countries we pay tax on smokes for the services we engage in our weaknesses of dealing with what we cannot deal with ourselves ... These include the area that the smoke travels and other people whom may be affected by that smoke . Other problems arise with the ash being littered and the cigarette butts and saliva .
