I don't get this thread at all. Flushing cannabis may not be as important here in Canada today due to legalization years ago, but it still has merit in many other countries even to this day. I advise watching the amount you flush. Having your toilet backup and spill water and weed all over your bathroom floor can be an issue while the police are knocking at your door. I suggest flushing no more than half a pound of weed at any one time to prevent such outcomes if you have the time to do so. Flushing cocaine isn't normally an issue due to its high solubility and smaller form factor. Just be careful when forced to flush your weed though if you choose to do it. I know this from prior experience gained decades ago.
