I   Had  This   Idea   That   You  Could 
  Construct Reality checks (As For Lucid  
 Dreaming, Where You'D  Learn This  Habit 
 Of  Trying To  Sneakily Break  The Rules 
 Of  Causality   Or  Physics,   Such   As 
 Flipping  A  Light  Switch  To See If It 
 Actually  Turns   Off   The  Lights,  Or 
 Trying  To  Get  Your  Hands   To  Phase 
 Together. The Thought Being  That If Any 
 Of The  "Checks" Actually  Worked, You'D 
 Know  You  Were  Dreaming)  For   Datura 
 I Thought, You Could  Get  In  The Habit 
 Of  Throwing Things On The  Ground, Like 
    Pens. Meant To Portray Cigarettes,    
 Because Everyone Who Does  Datura Smokes 
 Cigarettes.  (They In  Fact Aren'T,  And 
 So   Sooner  Or  Later   The  Cigarettes 
 Disappear,  And They  Search The Ground, 
 But Nothing'S There.)  Throwing Pens  On 
 The  Ground  And  Picking Them  Back Up. 
 And Be Really  Concerned If They Weren'T 
               To Be There.               
 This  Is  Probably  Not  How  Deliriants 
 Work.    But    I   Had   The   Thought.
