Which sample was ever found with cyanide?
The one in my " for example " - " theoretical " example . Its there to make the point more clear . The worst i have seen was a report of lead dust in a sample .
" No test in the world tests for everything "
That aplys to both sorts of test . When we test we want the best , most reliable FULL results so we go for the best we have ........ like courts and drug testing labs do . Colour tests have massive holes in them ...... and when we use those tests we dont know if .... and if what is in the hole = It isnt worth doing except for what they are specificly sold for = for example concerned people ........ police and parents can test substances to see if they have " illegal " content . Other than that i see no use .
" I think it's easier to talk specific examples instead of non-existent or unlikely hypothetical examples.
OK . In western europe there has been very much outdoor grass that is said to come from serbia . There have been newspaper reports and TV documentrys about it . Its fact . Some of the grass was tested and was show to have pesticide on it . Sometimes i have had outdoor grass thatmade me sneeze a lot . Was it the pesticide ?
We also see grass that has been poluted with commercial products to make it weigh more . One name was Brix or bricks ? Sometimes there is so much on it that the grass snaps , crackles and pops when its heated .
Next ...... since the secret of washing grass got out about 15 years ago its been used to cut hash . That means that the best quality powders are washed in cold water and the fat is then mixed with the third quality powder . In that fat there is a little of the good powder = Joe public gets something that has much more fat in it ......... and thinks " Hey WOW !!!!! ...... top quality resin " and pays MUCH more for it . The hit he is getting is to a large part from the fat that is plastering his lungs = poison , poison gasses and lack of oxygen . Their lungs get " glued " up = again lack of oxygen = They think that they are high .
Now thats gone a step further and " they ' are putting other fats in = fat that doesnt come from the cannabis plant . What is it ? I have no idea . I have seen / extracted at least two sorts and they were tasteless .
That " hash " with the extra fat in it is the equivalent of smokeing candles . One of the main causes of death in the middle ages was breathing in the fumes fom candles and oil lamps .
Would colour tests help ? To detect pesticides ? To identify added weight fillers ? What about othe things that have been found in commercial " hash " from shredded plastic to old LPs ?
Or would it have to go to a profi lab ?
You say pregnancy test . EXACTLY . Thats a yes or no question . The same as colour tests . It doesnt show what sex the baby is or its weigh or its blood group . Colour tests just show if a chemical or chemical group is present . That shows nothing about the " safety " or aceptability of the other contents = It does nothing to help drug harm prevention .
" what is the alternative you are offering "
I am not offering an altenative . I am trying to make clear that those tests are VERY limited and that people can get a false sense of security by useing them . Thats why drug test organisations , governments and courts dont use them ...... and why profi labs offer the tests .
The original poster asked a question and was told to test things . Colour tests are only usefull in rare situations
I'm also trying to give a new member a bit of suport . He came and asked a question and was answered . I am trying to put those answers in perspective .
