LSD looks something like this;


         CH---CH
        //    \\ 
HN-----CH       CH        
 |      \      /           
 |       C====C            
 |      /      \                        
HC=====C        CH===C   H            
        \      /      \ /           
         CH---CH       C               
               \      / \
                N----CH  C=O                          
               /         |                       
              CH3        N--CH2--CH3       
                        /                         
                       CH2                      
                      /                         
                     CH3                        
                           

Needless to say, it's not the world's easiest synth, being much more complex than ecstacy or speed.
