i think the answer is no because we know now that weed is not physically addictive by itself - if people turned up with withdrawls from pre rolled joints then that would be an instant problem for the companies..
but, aren't stoners connoisseurs of weed? we would take deep interest if this was discovered or even rumored about our mass product right? i would not stand for it and i assume what you are describing would be a highly illegal business tactic.. perhaps we will have even minded pot smoking individuals at all levels of the mass cannabis industry who will not let that happen.. i think it is a pretty remote possibility - lots of people would know about it - they couldn't do in en mass in secret for long with so many people having personal interest in the quality of theirs and other peoples' weed..
that's what i think..!
