A useless post from an ignorant person. So the symptoms he, and many others, are discussing here should all just be dismissed because you blindly refuse to believe that cannabis can have a negative effect?
These people have been consistently topping their system up with a chemical for years - upon no longer receiving this chemical input they are clearly having considerable effects. Whatever you want to technically classify this as, they are physical effects resulting from an addiction. If this is a mental addiction it is still causing physical effects. So your dismissive little comment was as insightful as it was helpful; not at all.
Obviously no actual evidence or credible sources to give, undoubtedly got this opinion from other naive individuals posting pointless pseudo facts online.
When younger and went without it of course it wasn't as bad..... The worst was anxiety/no sleep, but nowadays it's TERRIBLE.... The worst of all the symptoms has to be the dry wretching + bad stomach (for me)! Absolutely unbearable so hopefully it will get better over time and maximum respect to those who shared their experiences.... Nice 1/All the best...
