Are you purposely ignoring the part where it says
"At any one time, there should be the correct ratio of responsible adults who must not consume alcohol (a minimum of two adults and risk assessments in place"
And
"In general, adults should not consume alcohol in the presence of under 18s though it is accepted this might occur in certain circumstances such as fundraising and social events. This should be assessed by risk assessement"
So Leaders do drink. Yes when the children are in bed but they do have a drink.
The older teens drinking are on camp with their own Explorer pack. And it's a third of a can of Carling and that's it. They wanted to try it, they were allowed, 2 of them had a mouthful and didn't like it.
The other Explorer group in our District had a safeguarding issue where one of the 16 year old explorers drank half a bottle of vodka in the woods at the back of camp, they had taken it in their backpack which had been hidden from parents and they snuck out of the tent when the Leaders had gone to bed to drink it.
It opened up a whole issue that alcohol/drugs education isn't be pushed enough and neither are the dangers around abusing it, not at school, home or anywhere else. The more you make it forbidden and hide it, the more appealing it becomes.
I was raised in a house where nothing was off topic, nothing was hidden. My Dad gave me a shot glass of weak cider when I was 14 because all my friends were going off drinking and I wanted to know what it tasted like. It was grim and I never touched it again or attempted to buy it to sneakily drink it. The taste put me off. My son has dipped his finger in my ales to try and doesn't like the taste, whereas his friends (14/15) are sneaking out cans of lager to drink.
When he moved to his Explorers group, I was asked if i consented to education around alcohol and drugs and for the Explorers group to be a safe place and I consented, why wouldn't I? As many people who can help with this education and not ignore what could happen is much more beneficial to me than banning and hiding it.
I'm not associated with Scouts in any way other than my child has gone through them and I'm more than happy with how they have played their part in shaping my child. He's the top shooter in the county, can light a fire, pitch a tent, shoot and skin a rabbit, abseil, rock climb, swim, read a map, use a compass, cook over an open fire for 20 people, can mix in groups of people who he doesn't know, is sociable, confident and capable. He's nearly completed his Platinum QSA, is off to Korea for Jamboree and is also a young leader with Cubs.
But you are daft to think alcohol isnt involved in Scouts, along with things that would make you want to keep your child wrapped up forever.
Wait till guns and knives are involved.
